Well....we'll see what you guys think of this one. I know it's a little different from usual but once I read about a few of these stories I had to make a video about the topic. Hope you guys enjoy! Next video will be about the mathematics of crime and some of the things seen in the show 'Numb3rs'.
Loved the video. I also liked Numb3rs and cannot wait to see what you do with it. Rossmo's Formula blew my mind Edit: loved how you perfectly generalized people on the interwebs
We interviewed 1000 people that have played russian roulette before. 100% of them survived the game. Conclusion: Russian roulette is completely safe to play.
@@boombam9611 no no haha the only way someone could be interviewed after playing Russian Roulette was if they survived. It is impossible to interview people who have played Russian Roulette and died because of it, so of course any such interviewing would yield a 100% survival rate.
This one is called survivor's bias. There's a good example of the Brits determining which parts of a fighter plane to add armor to, and they used the planes that returned to make the decision.
I found it disconcerting that I couldn't find the median life expectancy for most countries. Mean is very unreliable. It can be warped with outliers and noise. Median is far more reliable. So when trying to compare the U.S. to Japan, I only found that the U.S. median life expectancy is 84.5. I have no idea what Japan's is.
I read one on which countries had the largest increase in murder rates. New Zealand had an increase of 300 percent , however if you looked at the actual numbers they went from one murder in a year to 3 . I think I would be willing to take my chances
That's per 100k population. To put it in perspective, for that equivalent year, that's a 52% chance of being killed compared to living in USA. However, two years prior, there was only a 13% chance relative to USA, with a roughly 1/5 chance over the past 10 years. The reason I point out USA is all the gun-related deaths vs. NZ which has much stricter firearms laws. However you look at 2.6 vs 5.1 (rounded) / 100k being high or low, it's interesting how many people say NZ is so safe and USA is dangerous -- future years will determine if NZ retraces lower.
@@junkbond4882 According to wikipedia New Zealand had 126 cases of intentional homicide in 2019, a rate of 2.6/100k. During the Christchurch mosque shooting that year 51 people were killed, i.e. nearly half of all intentional homicide victims in 2019 thereby close to doubling the rate per 100k. The 2017 mass shooting in Las Vegas killed 61 people. With total intentional homicide victims north of 20000 that year this event didn't have any impact on the rate per 100k for the US. Context is key...
I remember my algebra teacher telling us about this, saying that statistics show people with bigger feet are better at math. None of us could have guessed that the statistic studied all ages, so it included babies and toddlers.
That's why in my AP stats class my teacher made it a huge deal to put the context, the group we where studying, any stratification, the way we got the data, any sort of bias that could came up, and error we couldn't account for. Stats are so easily capable to be miscommunicated even if you meant well. Someone could take a number you put out there in good intention and use it to push an agenda while ignoring key aspects of the stat. A stat isn't just the probability, it's the context and situation it was taken with.

Magic Gonads Here‘s the thing: 100% of X is X. So if X increases by 100% (of X), it increases by X, so there‘s an additional X is added to the original X, which means that it was doubled. If X decreases by 100%, it decreases by X, so there‘s X subtracted from the original X, which means that it went to zero. Clearer now?

@caprice.t One thing though. Its not easier, its just more likely. For the average person It would be easier to get tô work for Walmart, but since only people with a decent level of instruction apply to Harvard, its more likely that these people would succeed, but for a regular person It would be almost Impossible
I doubt Walmalt has a 2.6% acceptance rate, but it's not hard to imagine that out of all the Walmarts in the world, one of them somewhere has a 2.6% acceptance rate due to an overabundance of unskilled workers applying.
Lessons: 1. In graphs, always include 0 2. When giving percentage changes, always provide both percent increase (if it doubled, its a 100% increase) and percentage point increase together (if it went from 1% to 2%, it increased by 1 pp)
Including 0 isn't actually the pertinent part. What's important is having a consistent scale that includes 0. You can have a graph that includes 0 but also has a break in its axis. Like if you have a graph with data in a field that goes from 0 to 100 but all of the data is grouped in the 80s, you could have the axis of the graph go: 0, 10 ... 70 80 90 100. This includes 0 but still suffers the same deceptive look as if it didn't.
@@Strawberryfreak Well yes but that's kinda besides the point. It's easy to just tell people to think more, but the thing is people might not know _what_ or _how to think._ There's a difference between telling people to just be critical and teaching people to think critically. That's where knowledge comes in. Knowing there's a significant difference between percentage increase and percentage point increase is something to be learned. Or knowing how much it matters how the data was derived and out of which group the percentage is drawn from. It's never just "think about it first", it's also realizing what there is to think about, what do we mean by the fact points given. Out of those specified definitions and the context, a "fact" means nothing at all. Not everybody, without being taught to, realizes this matters. It's one thing to be sceptical about a statistics in a title of a news article. It's a whole another thing to know that news headlines aren't statistics, that just because something was said, the reality of the matter is only revealed once you know the details. People also easily assume a moral value for pieces of trivial information. Just saying the rate of dropping out of studies has increased, for example, doesn't mean we're saying it's a bad thing. We aren't saying anything at all about whether it's good or bad with that piece of knowledge unless we specify why and justify such moral evaluation separately. This is also one of those things a lot of people don't necessarily know or realize to question. Categorical scepticism isn't necessarily smart either, and this idea of never trusting what we're being told instead of practicing curiosity and aiming to _know_ more is what has contributed to mistrust in media and authorities of information. It goes from "think first" to "don't trust at face value" to "don't trust media" to "we're being lied to and new information should be categorically rejected because authorities of information are by nature untrustworthy". No, the point isn't to be sceptical, it's to understand what it means to say certain things and why it matters how things are spoken about. Being sceptical for the sake of it paradoxically doesn't make people any less susceptible for being manipulated, in fact less so.
THAT WRONG you simple do not know statistics if i put half of your body in the freezer, and but half of you in the oven , and we make statistical analysis of your body temp we will get your body is in IDEAL temperature of course we know that you will die in this scenario does statistic lie?? NO the problem is YOU and you do not release what the number represents it not a problem of statisitc mate its a problem that people have not idea what the number represent
@@sonaruo That is rather harsh as OP did not say that statistics lie. He, in fact, stated that any story you want can be weaved by using the same data. You just decided to take the moral high ground when OP's claim was completely valid. I think everyone understands that statistics by itself is not the evil here. It is willful or unwitting use of incorrect or partial statistics that can potentially cause lot of harm.
@@AnkhArcRod sorry mate but the wording is plain wrong "whatever story you want to tell" no mate you cna nto use the math to say that blanc is white and white is black you simpel can not. but if the people do not know the numbers and the precise wording then people will assume something different because they consider the number represent something that it is not thats not a fault of statistic or that statistic said that to begin with example is the 100% and the 5% raise the wording is not the exact same its tiny different so you know how to use that number they give you since they are 2 different things the 100% is the rate of measurement while the 5% is the net increment. when you are given that the wording is slight different so you can say what it is and use them properly. now if the for the people the rate of changing something and the actual speed is the sam eis ther problem my math professor said this word of wisdom you think you do nto need math, what you teach today you will never use, but these numbers will be used in your every day life and because you will be unabme to understand what they represent they will maniip[ulate to do what ever they want. because he have books written , we teach something to people it does not mean that all people will understand it and comprehend it geee if that was truw 100% of the population will be scientist with doctor level and we will be going in another galaxy to settle down by now. and statistic is easy and real straight forward to do it if you want real massacre go is probabilities the majority of the problems are counter intuitive and many times to sovle them and be sure that its the correct one we end up brute force the problem
@@sonaruo The OP of this thread basically said the same thing this video said. It is EASY to use statiscs to form a story that you want to happen, or you can use data to grant the impression you want by with holding context. Yes if you do not understand the data your more likely to belief it but if I said out of 1000 people who applied to a job with 400 openings 0% percent of women who applied where accepted. Its very easy to understand no women where given a job. This is the sort of situation that was talked about its miss leading and with holding info. If I told you 1000 people applied to become a male stripper and 1 women applied who did not get the job is very different intent of presentation to 100% of the women who applied did not get the job. I hate % with a passion its easy to mislead as a 100% increase is alarming but you can also say there was a 5% increase for the same data. I mean you can even use that term a 100% increase if the sample size simply decrease. It depends if you look at all the data or just the increase. Look at house prices in NZ and you will see a misrepresentation of what they are increasing by as its better to use the 5% but if you want to create a panic or a rush to do something use the 100%.
Within my statistics class in college we actually had to identify misleading charts and graphs and explain how they were designed to mislead. I saw graphs that were upside down, with offset scales, and even the use of specific colors to elicit a response.
So...AI have been removing my comment several times now because of certain words. So for this comment to make any sense, I need to clarify what I mean by certain words: LowVibb19 = that thing that is spreading around the world that people are shit scared of even though it has a 99% survival rate. Max = That thing that they want you to take into your bloodstream so that a certain industry can earn billiions of dollars even though it doesn't even work as intended. Now here's my comment: Here's another one for ya: You can also cheat with the statistics with how you define something. For example: They don't define a person as being fully Max'ed until two weeks after they've had the 2nd LowVibb19 Max. So anyone who gets seriously injured or die right after the first Max or within the first two weeks after the 2nd Max, will be defined as "un Max iated" in the statistics. So all the hundreds of thousands and maybe millions of people world wide who have been seriously injured or died from the LowVibb19 Max will not be counted in the statistics. Clever, huh? I personally know several people this has happened to.
yup. especially because of how messed up the case a whole was. they really fucked that woman over for a disease people are only just beginning to understand

Man I teach Excel. And for some reason Excel automatically sets other number different than zero in bar charts. The user has to perform some extra steps just to make the bar chart look like a real comparison.
It depends SOOO much on context, though. If you were showing a graph of a person’s body temperature with vs without medication, starting the graph at 0 would make no sense because you would barely be able to tell a difference of 4 degrees, even though that can mean the difference between a mild fever and someone needing hospitalization.

I have a degree in statistics. You did a very good job explaining these nuisances and yet this is still only scratching the surface of how wonky and manipulative statistical techniques can be.
It is a really good start though. I can't seem to reach anyone that doesn't already mildly understand how a statistic is even brought into fruition, nevermind the why. This introduction on the topic will likely save me at least an hour of my next conversation when pointing out the way media covers current events. Such as the scamdemic and inflation, or our country's spending vs GDP. These media outlets utilize these same techniques to sway people into voting for Representatives that are going to push legislation that, at the core, doesn't make any sense.
I don't have your credentials, but I do have 6 undergraduate and 6 graduate credits in statistics. I agree with you that David did a good job but there are so many other ways people lie with statistics. One of the big ones is when a single study comes out to prove a point and it's taken as gospel. Most people aren't aware of the need for an independently replicated study that produces the same results, they just assume the solo study is valid.
@@danielreshenterprises6174 well said. I agree 100% with the notion that one study without peer review is opinion, not science. The great thing about science is that findings are open to be replicated and if there are different results, we can all learn why. The best question and, in my opinion, the beginning and demise of our mortal selves, starts and ends, with the question, "WHY?".
@M M that is a very good point. This is where intellectualism and understanding of where the "peer review"originated from, comes into play. I preached to my son constantly, who recently turned 18 years of age, that the device that is in his pocket has unlimited knowledge. Back in my day we had to consult the encyclopedia Britannica. It is much easier today to learn about something, anything, that we don't already know.
It’s almost like the context of data is removed on purpose to generate a narrative that looks better for a particular group. It’s a weird world where people both don’t believe in numbers but vow by numbers when it’s convenient.
Most if it boils down to the fact that most people are not mathematicians, but also don't want to seem dumb by admitting they didn't learn enough about mathematics to understand what the numbers actually mean. if people would worry less about what they seem to be and start to worry more about what they actually are, this might chance, I doubt it will be any time soon.
One of the troubles there though is the hired gun. In the video example the prosecution was able to hire a mathematical gunslinger to argue their case for them. Either he was incompetent or dishonest in doing so. The defense was apparently unable to find a gunslinger of their own to explain the problems with the prosecution's argument. Not everybody's lawyer happens to date an expert. Whatever else I did with my degree in math, I was resolved that I did not want to be a gunslinger for some corporation (or think tank with an agenda). Yet doubtless I might have made a better living as a gunslinger and be highly regarded in society. I might even be able to tell myself that I was shooting on the side of justice.
@@BlacksmithTWD This is part of the problem definitely. At the same time, there is also a large element of confirmation bias as OC says. If it supports our narrative or fits our worldview, it's extremely credible and transparent. If not, we find 1,000 things to criticize about it.

I ran into this recently with my job as an auditor. We evaluated the reasonableness of a company’s marketing expense by comparing it to revenue. The idea was that if their revenue went up, it was due to increased marketing expenses (I know there can be other factors too). Anyways, most months their expense hovered around 2% of revenue. One month it was 3.5%. My staff told me “that’s less than a 2% increase; it’s very trivial”. I said “that’s a 60% increase- it’s worth looking into”.
I spend the same on marketing each month and only make adjustments periodically. If sales are up one month it might be 5% of sales spent on marketing. If sales drop for a month it might be 8% spent. But I didn’t change what I spent.
@@fivebooks8498 Since your marketing budget is fixed, if sales are up next month then your marketing expensive percentage (MEP) would be lower than 5%, if sales are down compared to starting month only then your MEP would go higher than 5%.

People should understand the difference between "percent" and "percentage point". 5 in 100 increasing to 10 in 100 is a 100 percent increase, and also an increase of 5 percentage points.

No. There is never a 100% increase when something goes from 5% to 10%. For example if you where to ask all the employees of company A if they enjoy work and 10% of them say no, then you ask again a year latter and 20% of them say no is that a 100% increase of people who do not enjoy there job or is there 50% decrease in staff. The only thing you can draw from that is 10% more of the total staff is unhappy. If you where to say that last year we had 10 unhappy employees and now we have 20 yes that is a 100% increase, but that is a different question. Question one what percentage of our staff are unhappy as of x year Question two what percentage of our staff are unhappy as of x+1 year.

Keeping this in mind is very important, especially in the world of media. You've shown how differences in presentation can twist public perception of an event. Now add the arbitrary choice of which piece of information is covered, the wording as well as many other factors and you can be manipulated, on purpose or not, and end up believing something completely untrue without anyone having lied.
For the “5% or 100%” question, the correct way to say it is either "the rates has increased by 100%", or "the rates has increased by 5 percent points". if you say the rates has increased by 5%" you mean that it has gone up from 5% to 5.25%.

That is why in those cases, it's better to just say double the amount of students is failing from previous year; present in the article, the total amount of students, how many of them are failing, then present what percentage that is of the total. But I guess click bait etc prevails, and 100% seems much more dire and dramatic... It's a good rule of thumb, that if an article uses statistics or percentages in general, but avoids mentioning any numbers, calculation and similar for that statistic or percentage; you better be suspicious that the article perhaps has an agenda, otherwise is untrustworthy and/or in the least, is bad journalism anyhow! Seen many bad examples of it mostly being the latter of those...
@@MisterL2_yt 'increased by 100%' alone is valid too. Although it would be better to say: "rate increased from 5% to 10% of student population per year, making it a 100% increase" or "the rate has increased by 100%, from 5% to 10% of student population per year."
Sarcastic Hue The statistics for corona virus will never be accurate. For one, there are people who get infected but never show symptoms,plus the fact that it takes to weeks for symptoms to develop in the first place. Also, in the UK, they on,y count the people who are hospitalized due to Coronavirus. The numbers will always be less than the real amount of cases.
DocInAbox They’re starting to do that in the US too. You get tested if you’re obviously sick. If not, no. Because that will push down the stats on how lethal this really is, and people can’t seem to figure out for themselves population vs. fatalities, and figure out the percentage on their own.
@6:40 I teach English in Japan, and a lot of my students are businessmen who have to give presentations. I always teach this distinction to avoid being deceptive, or just blatantly wrong. The way I say it is this: 5%--->10% should be said as "Increased by 5 percentage points" or "Increased from 5% to 10%". There's absolutely no ambiguity that way.
That's honestly the way I was thinking about it as well. That is, there's needless ambiguity caused by the language used in those phrases. Of course, if your intent is to sensationalize the event you'd always pick the "increase by 100%" line. Regardless, since there is no real difference between the two assertions, it comes down to semantics.
Actually, saying that it increased by 5 percentage points can be misleading. For example,to me, the pill example he gave was totally justified. Nobody cares about by how many percentage points it increased, they want to know how likely it is that they would die. And here, they would be 2 times more likely, which is extremely concerning
@@samylemzaoui2298 I'm sorry? A 200% increase isn't concerning at all, if the original death rate was 0.01%. That would mean I now have 0.02% chance of blood clots instead, which is an increase of 0.01 percentage points, which is much more honest than saying "by a 100%" The one showing you how much more likely you are at dying is the percentage point one. Because double nothing is still nothing. Let's say you're 10 times more likely to get hit by lightning if you're holding an umbrella. Does that dissuade you from ever holding umbrellas? No, because you know the original chance was slim already. Hope you get it, now. Cheers!
@Salah Eddine H Yes but if the old pill has a 1/7000 chance of causing blood clots, and the newer pill increases that chance by 100%. The odds are now 1/3500. Putting it this way the odds seem significantly more likely. Or perhaps this is just another way statistics lie.
@@SalahEddineH but saying "increased by 0.01"makes it seem like it's the same as before when the product is litterally two times more likely to kill you than the last one. To me, a 0.01 percentage point increase is not as important depending on the original value, but saying that it doubled is as important no matter the scale. I don't really see how .01 is the best indicator of how much more likely you are to die like what conclusion can you draw from that as a non-statistician ? And btw i would never use an umbrella if there's a lot of thunder for this very reason
Statistical probability should never be allowed in court. It has no bearing on anyone’s guilt or innocence. That is why we use witnesses or physical evidence. Great job my hillbilly friend.
yeah I think that it's now no longer allowed in court. There are so many ways to make it look like one thing and be a totally different thing. The more qualities you rack up, the less likely a specific person in a group is to match that description, but it still doesn't prove it *was* them, it proves it's unlikely it wasn't them. It feels dirty to put someone behind bars not because someone saw them do it, finger prints were found and they had intent to do it, but because it's unlikely that anyone else fitting the description of the eye witness(s) exists in that city. I feel like it goes against the "innocent until proven guilty" rule of the courts.
Best one I ever heard. Back in the 60s, the USSR compared Soviet built cars with US built cars. These were the only cars compared. The US cars killed the Soviet cars in every way. The Soviet state reported that the Soviet built cars came in second and the US cars came in next to last. Both were absolutely true and absolutely misleading.
Three statisticians went duck hunting. When a duck flew overhead the first one shot and missed 3 feet to the left, the second one shot and missed 3 feet to the right, and the third statistician yelled "We got him!"
This has just made me realize how easily I believe anything presented in a professional manner, and how easy it is to downright lie through a small omission of facts. It is truly scary.
I don't know why schools push calculus much harder than stat, when stat is actually useful in life for most while calculus isn't. Maybe because calculus is more fancy? Hell, statistic isn't even required for all math majors, whereas courses like analysis on manifold is. The number of people who might find the latter useful probably won't amount to four figures in the country. And if you subtract teachers, barely three figures. It's right "up there" with art history.
Here's my favorite: An airplane comes back from an aeriel battle. The data shows that most of the damage was on the wings, the fuselage, and nowhere near the cockpit and engine. So, the engineers decided to refine the armor on the damaged parts of the plane.
Using statistics in court worries me a little since people should be proven guilty, not assumed guilty based on statistical models that are below 100%.
@@mikaelvirji5807 Things are rarely 100%, but if there's not a convincing case and evidence then I think statistics should not be used in an attempt to sway the jury.
Very very good video. It’s so important to understand statistics today. In the workplace. In the news (especially the way media reports covid stats). A constant tactic of news is to say the such and such has doubled or gone up 3 times without stating the denominator. Correlation is another common tactic I see in the workplace and in the news.
@Basically Al Capone in legal Look, this isn't basic intuition. not everything is JUST correlation either. You need to learn a p value and a hazard ratio, and learn to read a forest plot. stats arent this easily understood and people overcorrect, thinking EVERYthing under correlation is just that. No, there is a point where the chance of correlatiom is lower and lower and thus incresing chances of causation, especially with multiple explanations. This would be like observing the sun has gone up every morning for the past 2000 years. we don't know it will go up tomorrow, but it becomes so statistically impossible for it to not go up tomorrow, plus the use of astrophysic calculations, that it is "causation". in reality, everything is just a correlation we arbitrarily bump into the causation category until a better answer is found. This is typically based on the effect on humans. One of these examples would be chances of lung cancer from smoking. It's technically not causal, but do it enough in a population, and someone will invariably get it 100% of the time.
@@jenm1 If you look at the total deaths in the US compared to the last 5 years you find something weird. They have not significantly risen this year. Then look at deaths by cause in the US for the last 5 years. You will find that they are remarkably consistent up until 2020 when deaths by covid suddenly rise AND deaths from heart disease, cancer, influenza, ect. suddenly fall. So we must consider if something about covid or the circumstances around it is simultaneously good for heart disease, cancer, AND a large number of other causes of death or if (due to financially incentivizing hospitals for covid) we are massively misreporting deaths as caused by covid. Look at the context of the numbers. Not just the raw data. I wish you well.
Anyone who says, "The statistics speak for themselves!" is about to speak for the statistics. The louder they are, the less likely they are too understand Bayesian Prior Probabilities.

I mean i could just use quantum tunneling to explain how you murdered someone across the world from you, and as long as i provide accurate math to show its possible, i could get you convicted for it Its easy to convince people you are right if you convince them you are smarter than both them and the person you are acusing
@@thezyreick4289 Which just proves the fault in our laws. Why exactly are we giving 100% people caught red handed defense attorneys? Why are we holding people in jail for 25 years or life when they commit acts like murder, kidnapping, pedophilia, rape, trafficking a type of kidnapping, torture, necrophilia and sick acts instead of executing them. Why are we sending addicts to prison. If you cannot prove someone did something with evidence, you shouldn't be able to convict them at all. Did anyone see it? is there any evidence of it? did they admit to it? were there any witnesses? any foul play like poison or a hitman etc.? So they should go free. It's dumb. Basically, all a good lawyer has to do is convince people of innocence even when evidence shows they are guilty, or convince people of guilt even if no evidence is present. Defense attorneys literally make up things for criminals and use it as a defense lol we all know this.
Not really sure if its true, but i heard a story that after the British army started issuing helmets to their soldiers in WW1, they saw an increase in head injures and so people thought that the soldiers having helmets made them take more risks or get injured more. In reality a statistics person looked at it and realized people were getting more head injuries because more people where surviving hits to the head by shrapnel.
I've heard a story like that, and a similar story about airplanes, where all the ones that came back from war were damaged in certain places like the wings and other non-essential places.
@@ETXAlienRobot201 I'm not sure if ww2 bomber were made like this, but the close air support a10 thunderbolt was made so it can fly with half of its wings, also a lot of the bomber wings were probably empty space where bullets and flak just went right through, with some control lines for the flaps.
true... still, losing wings wouldn't be the best thing to do, they are there for a reason...lol also, this would depend on the craft, if the ENGINES are mounted on the wings, well... you would then have fuel leaks and engine failure to deal with, potentially losing the flaps or control lines for them probably wouldn't be ideal would also depend on the amount of damage received to the wings (or any other part, for that matter) for all the planes that came back, how many didn't? of the ones that did not return, WHY? there are questions here not being asked, which also is were i was going at. every single part of a plane is pretty essential, some might be more expendable, but i don't think a plane whose wings resemble swiss cheese is going to have an easy landing/flight. probably the safest part to lose would be the landing gear or the weapons. ofc, in a fight, losing guns/ammo/etc... isn't ideal, and landing gear still exists for a reason, so landing would be EXTREMELY difficult/dangerous. also, it's more likely to just fail or break during take-off, anyways. not much reason to target it when you could target wings/fuel/props to potentially cause the craft to lose control/thrust or explode/burn. and yet another question to be asked, how many craft had to abandon their mission because of damage sustained during battle? While in the long term, having survivors might be a good thing, how many of those who survived survived at least in part because of a retreat or rescue? In the short term, both of these are a defeat. They tend to represent missions that fail or barely succeed with high casualties. Let's just look at bombers. After a war, sure, you can just brag or state about the kinds of damages that they can sustain before crashing. (yet an additional statistic : the pilots, themselves. a less experienced pilot might be more likely to crash from minor damage to his craft than an experienced one whom could easily land/fly with half the wings missing, maybe even a failed/damaged control line or flap) Or instead, maybe you should look at: of all the bombers commissioned and launched, how many survived? of all the missions that took place, how many succeeded? how many bombs actually hit their exact targets? did any bombs not perform properly? how many casualties per mission, successful or not? were any of the targeted regions/countries more difficult to attack? As this video says, statistics easily miss-lead. If the article merely mentions surviving planes, then... Can't say I'm impressed. That just says some (in the unlikely event, all) of the craft survived. It doesn't speak for their effectiveness in what they were set-out to do, or how many planes did NOT survive. That's more important than counting bullet holes and plotting locations. Due to modern medicine, you could survive many previously life-threatening stabbing/shooting injuries. Possibly without a permanent disability. (besides PTSD) It's be easy to skew this as (just making some number up as an example) "40% of people shot in the chest survive" This would discount medical care, time of response, individual fitness/health, preparedness for a bullet to the chest, etc.... It also discounts what part of the chest was shot. being shot straight in the heart would be considerably worse than being shot in a single lung. Wouldn't be surprising to see higher death rates for taking a bullet to he heart, and probably the majority of fatal chest-shots being to the heart. Oh, and just thought of these: How many bullets were fired? What were the bullets made of? Were the bullets specialized in some way to cause more damage? And when you combine all these facts, the supposed "40% survival rate" of being shot in the chest" takes *several* bullets to the chest.
If some bullets hit your wing, you can keep flying. It wouldn’t cause the wing to fall off. In the engine, just one bullet could damage a key piece of the engine, making you lose control of the plane
9:00 I had a lit math teacher and he was teaching us about this stuff. He said there was a study where, when the math teacher smiled a ton, his students ended up having better grades. There was correlation. But it was the other way around. The teacher was smiling because his class was doing well
That may be true in that case, although I doubt it because it would more likely be a feedback loop where both factors are influencing each other. Say the teacher started the school year just after attending the funeral of his mother. His students go from a C average to a B average in the first month. Did the teacher's mood change because he successfully grieved his mother's passing or because his students are getting better grades?
fake , teachers don't actually cares about their classes and are fucking statists who fantasize about all authority and who makes profit off of the shitty garbage fucking school system , they don't care they're just here to abuse of their power and to make everybody suffer like they get turned on by sending someone to detention if a teacher is smilling it's because he loves the suffering of his students , but the good thing is , a smile makes it much more easy to knock their fucking teeth out

The thing with percentages is that they represent a ratio between two absolute values, so whenever you mention percentages it is important to know what that ratio is in reference of. So when ever someone says "something increased/decreased by X%," what they are missing is the second part where they say "relative to Y".

Isn't "the average person" similar to "a randomly selected person"? Would a way to create the same effect be "the average number of a person's hands is less than two" or do you have something better?
@@JonathanLyons7 "a randomly selected person " is the most common value, also known as Mode. The average is just compiling and comparing, most people have 2 hands, then you have a small amount of people that have 1 hand so the result would be something like 1.993 (I'm making up the number and also taking the possiblity of having more hands rather than less out of the equation as I assume that is at least less common). Which technically is less than 2.
@@JonathanLyons7 so if out of 20 students, everyone gets a 50/100 then the one person gets a 0, the average would be 47.5, technically less than 50. The example given by the previous user highlights an extreme case of this

When I taught college-level statistics back in the 80s, I had one class session titled "How to lie with statistics" that went into examples just like these of exactly how people would try to mislead them with improperly used statistics. One of the other ones I covered was color scale manipulation with "heatmap" style graphs that use colors to indicate values. For example, a graph showing temperatures can influence what you think is "hot" or "cold" just based on what temperature is chosen as the midpoint of the red-blue transition. Or, two graphs can be shown side-by-side that have different color scales to make similar patterns look different, or vice-versa.
at first i thought 'okay, maybe that makes sense since presumably the people who use headlights more than people who don't are less likely to be in car crashes, and that would affect their 'health' but nah, i'm just dumb.

During WWII, the US government had research done on what parts of aircraft were most often damaged by enemy fire, to see if they could reduce aircraft loses by armoring those areas. After research was done, they had a list of aircraft parts that should be upgraded, but a senior official informed them that their research was done incorrectly, in that it counted what parts were found damaged on aircraft that made it back to base. He suggested that instead they should see what parts of aircraft were least often damaged on any aircraft that returned from missions, and to assume that aircraft which took damage to those areas had little chance of survival. So for example, lots of aircraft that survived missions came back with holes in their wings or fuselage, but very few aircraft that were hit in the engines or cockpits survived.

That's per 100k population. To put it in perspective, for that equivalent year, that's a 52% chance of being killed compared to living in USA.

So if X increases by 100% (of X), it increases by X, so there‘s an additional X is added to the original X, which means that it was doubled.

I doubt Walmalt has a 2.6% acceptance rate, but it's not hard to imagine that out of all the Walmarts in the world, one of them somewhere has a 2.6% acceptance rate due to an overabundance of unskilled workers applying.
Lessons:
1. In graphs, always include 0
2. When giving percentage changes, always provide both percent increase (if it doubled, its a 100% increase) and percentage point increase together (if it went from 1% to 2%, it increased by 1 pp)
Including 0 isn't actually the pertinent part. What's important is having a consistent scale that includes 0.
You can have a graph that includes 0 but also has a break in its axis. Like if you have a graph with data in a field that goes from 0 to 100 but all of the data is grouped in the 80s, you could have the axis of the graph go: 0, 10 ... 70 80 90 100. This includes 0 but still suffers the same deceptive look as if it didn't.
I think a big one is --> BE CAREFUL OF DRAWING CONCLUSIONS WITHOUT THINKING
@@Strawberryfreak Well yes but that's kinda besides the point. It's easy to just tell people to think more, but the thing is people might not know _what_ or _how to think._ There's a difference between telling people to just be critical and teaching people to think critically. That's where knowledge comes in. Knowing there's a significant difference between percentage increase and percentage point increase is something to be learned. Or knowing how much it matters how the data was derived and out of which group the percentage is drawn from. It's never just "think about it first", it's also realizing what there is to think about, what do we mean by the fact points given. Out of those specified definitions and the context, a "fact" means nothing at all. Not everybody, without being taught to, realizes this matters. It's one thing to be sceptical about a statistics in a title of a news article. It's a whole another thing to know that news headlines aren't statistics, that just because something was said, the reality of the matter is only revealed once you know the details. People also easily assume a moral value for pieces of trivial information. Just saying the rate of dropping out of studies has increased, for example, doesn't mean we're saying it's a bad thing. We aren't saying anything at all about whether it's good or bad with that piece of knowledge unless we specify why and justify such moral evaluation separately. This is also one of those things a lot of people don't necessarily know or realize to question. Categorical scepticism isn't necessarily smart either, and this idea of never trusting what we're being told instead of practicing curiosity and aiming to _know_ more is what has contributed to mistrust in media and authorities of information. It goes from "think first" to "don't trust at face value" to "don't trust media" to "we're being lied to and new information should be categorically rejected because authorities of information are by nature untrustworthy". No, the point isn't to be sceptical, it's to understand what it means to say certain things and why it matters how things are spoken about. Being sceptical for the sake of it paradoxically doesn't make people any less susceptible for being manipulated, in fact less so.
@@R3_dacted0that’s not really how graphs work. It would be too obvious if someone broke the axis up like that

You just decided to take the moral high ground when OP's claim was completely valid. I think everyone understands that statistics by itself is not the evil here. It is willful or unwitting use of incorrect or partial statistics that can potentially cause lot of harm.
@@AnkhArcRod
sorry mate but the wording is plain wrong
"whatever story you want to tell"
no mate you cna nto use the math to say that blanc is white and white is black you simpel can not.
but if the people do not know the numbers and the precise wording then people will assume something different because they consider the number represent something that it is not
thats not a fault of statistic or that statistic said that to begin with
example is the 100% and the 5% raise the wording is not the exact same its tiny different
so you know how to use that number they give you since they are 2 different things
the 100% is the rate of measurement while the 5% is the net increment.
when you are given that the wording is slight different so you can say what it is and use them properly.
now if the for the people the rate of changing something and the actual speed is the sam eis ther problem
my math professor said this word of wisdom
you think you do nto need math, what you teach today you will never use, but these numbers will be used in your every day life and because you will be unabme to understand what they represent they will maniip[ulate to do what ever they want.
because he have books written , we teach something to people it does not mean that all people will understand it and comprehend it
geee if that was truw 100% of the population will be scientist with doctor level and we will be going in another galaxy to settle down by now.
and statistic is easy and real straight forward to do it

we end up brute force the problem
@@sonaruo And despite that, OP has over 9000% more likes than yours. Where does that put you?
@@sonaruo The OP of this thread basically said the same thing this video said. It is EASY to use statiscs to form a story that you want to happen, or you can use data to grant the impression you want by with holding context. Yes if you do not understand the data your more likely to belief it but if I said out of 1000 people who applied to a job with 400 openings 0% percent of women who applied where accepted. Its very easy to understand no women where given a job. This is the sort of situation that was talked about its miss leading and with holding info. If I told you 1000 people applied to become a male stripper and 1 women applied who did not get the job is very different intent of presentation to 100% of the women who applied did not get the job.
I hate % with a passion its easy to mislead as a 100% increase is alarming but you can also say there was a 5% increase for the same data. I mean you can even use that term a 100% increase if the sample size simply decrease. It depends if you look at all the data or just the increase. Look at house prices in NZ and you will see a misrepresentation of what they are increasing by as its better to use the 5% but if you want to create a panic or a rush to do something use the 100%.
Within my statistics class in college we actually had to identify misleading charts and graphs and explain how they were designed to mislead. I saw graphs that were upside down, with offset scales, and even the use of specific colors to elicit a response.

@@rivershen8199 Whats crazy though, is that it still works even on people who know that.
So...AI have been removing my comment several times now because of certain words. So for this comment to make any sense, I need to clarify what I mean by certain words:
LowVibb19 = that thing that is spreading around the world that people are shit scared of even though it has a 99% survival rate.
Max = That thing that they want you to take into your bloodstream so that a certain industry can earn billiions of dollars even though it doesn't even work as intended.
Now here's my comment:
Here's another one for ya: You can also cheat with the statistics with how you define something. For example: They don't define a person as being fully Max'ed until two weeks after they've had the 2nd LowVibb19 Max. So anyone who gets seriously injured or die right after the first Max or within the first two weeks after the 2nd Max, will be defined as "un Max iated" in the statistics. So all the hundreds of thousands and maybe millions of people world wide who have been seriously injured or died from the LowVibb19 Max will not be counted in the statistics. Clever, huh? I personally know several people this has happened to.

It is a really good start though. I can't seem to reach anyone that doesn't already mildly understand how a statistic is even brought into fruition, nevermind the why. This introduction on the topic will likely save me at least an hour of my next conversation when pointing out the way media covers current events. Such as the scamdemic and inflation, or our country's spending vs GDP. These media outlets utilize these same techniques to sway people into voting for Representatives that are going to push legislation that, at the core, doesn't make any sense.
I don't have your credentials, but I do have 6 undergraduate and 6 graduate credits in statistics. I agree with you that David did a good job but there are so many other ways people lie with statistics. One of the big ones is when a single study comes out to prove a point and it's taken as gospel. Most people aren't aware of the need for an independently replicated study that produces the same results, they just assume the solo study is valid.
@@danielreshenterprises6174 well said. I agree 100% with the notion that one study without peer review is opinion, not science. The great thing about science is that findings are open to be replicated and if there are different results, we can all learn why. The best question and, in my opinion, the beginning and demise of our mortal selves, starts and ends, with the question, "WHY?".
@M M that is a very good point. This is where intellectualism and understanding of where the "peer review"originated from, comes into play. I preached to my son constantly, who recently turned 18 years of age, that the device that is in his pocket has unlimited knowledge. Back in my day we had to consult the encyclopedia Britannica.

It’s almost like the context of data is removed on purpose to generate a narrative that looks better for a particular group. It’s a weird world where people both don’t believe in numbers but vow by numbers when it’s convenient.
Most if it boils down to the fact that most people are not mathematicians, but also don't want to seem dumb by admitting they didn't learn enough about mathematics to understand what the numbers actually mean. if people would worry less about what they seem to be and start to worry more about what they actually are, this might chance, I doubt it will be any time soon.
*change
One of the troubles there though is the hired gun. In the video example the prosecution was able to hire a mathematical gunslinger to argue their case for them. Either he was incompetent or dishonest in doing so. The defense was apparently unable to find a gunslinger of their own to explain the problems with the prosecution's argument. Not everybody's lawyer happens to date an expert.
Whatever else I did with my degree in math, I was resolved that I did not want to be a gunslinger for some corporation (or think tank with an agenda). Yet doubtless I might have made a better living as a gunslinger and be highly regarded in society. I might even be able to tell myself that I was shooting on the side of justice.
@@BlacksmithTWD This is part of the problem definitely.

I ran into this recently with my job as an auditor. We evaluated the reasonableness of a company’s marketing expense by comparing it to revenue. The idea was that if their revenue went up, it was due to increased marketing expenses (I know there can be other factors too). Anyways, most months their expense hovered around 2% of revenue. One month it was 3.5%. My staff told me “that’s less than a 2% increase; it’s very trivial”. I said “that’s a 60% increase- it’s worth looking into”.

I spend the same on marketing each month and only make adjustments periodically. If sales are up one month it might be 5% of sales spent on marketing. If sales drop for a month it might be 8% spent. But I didn’t change what I spent.

The other managers looked shocked until I agreed with her and said "Yes, it has doubled. Now you do two instead of one". We all had a good laugh.
Lol,hope you didn't get fired for that.
I hope it was because she got a second employee and not because she has to do two appraisals instead of one for each employee.
@@jcsjcs2 It was a second employee under her supervision.
One of statistic's better uses is in the leadership preformance algorithm that includes the skill "sets" as productivity multipliers... 😁
A cool thing that my language (polish) has (and uses) that english really doesnt(that i know of) is having an established difference between "percentages" and "percantage points". You use the first one like multiplication so 5 percent + 50 percent[of 5] is 7.5% and the second one as adding 5 percent + 50 percentage points = 55%. This basically means that as long as you read the text accurately you wont be misled

Please update your data. ♥ ♥ ♥
going from 5% to 10% is 100% increase, but 5 procent points increase.
For correct mathematical therminology.
No. There is never a 100% increase when something goes from 5% to 10%. For example if you where to ask all the employees of company A if they enjoy work and 10% of them say no, then you ask again a year latter and 20% of them say no is that a 100% increase of people who do not enjoy there job or is there 50% decrease in staff. The only thing you can draw from that is 10% more of the total staff is unhappy.
If you where to say that last year we had 10 unhappy employees and now we have 20 yes that is a 100% increase, but that is a different question.
Question one what percentage of our staff are unhappy as of x year
Question two what percentage of our staff are unhappy as of x+1 year.
What are the numbers of unhappy people we have in the work place in x year
What are the numbers of unhappy people we have in the work place in x+1 year
5% is 5/100
10% is 10/100
10/100-5/100=5/100

It is true that you can't infer anything out of knowing only 2 percentages (not even that 10% more of the total staff is unhappy because which total staff are we talking about? if we are talking about the first one then you can't say that 10% more of those employees are unhappy because maybe they were fired later, the 20 percent has to do with the amount of people in the second sample, and if we are talking about the second one, again that first 10% has nothing to do with the second one.), but if you know that the numbers are the same then you can show that it's a 100% increace.

For the “5% or 100%” question, the correct way to say it is either "the rates has increased by 100%", or "the rates has increased by 5 percent points". if you say the rates has increased by 5%" you mean that it has gone up from 5% to 5.25%.

Thank you for this. I see statistical illiteracy and misrepresentation way too often
The 5% vs 100% increase scenario bothers me constantly, each and every time I hear about an increase I wonder which they mean.
That is why in those cases, it's better to just say double the amount of students is failing from previous year; present in the article, the total amount of students, how many of them are failing, then present what percentage that is of the total. But I guess click bait etc prevails, and 100% seems much more dire and dramatic...
It's a good rule of thumb, that if an article uses statistics or percentages in general, but avoids mentioning any numbers, calculation and similar for that statistic or percentage; you better be suspicious that the article perhaps has an agenda, otherwise is untrustworthy and/or in the least, is bad journalism anyhow! Seen many bad examples of it mostly being the latter of those...
I think we should more frequently use percentage point. That immediately tells you what is going on. Problem solved!
"increased from 5% to 10%"
"increased by 100%, now totalling at 10%"
would be valid
@@MisterL2_yt 'increased by 100%' alone is valid too. Although it would be better to say:
"rate increased from 5% to 10% of student population per year, making it a 100% increase" or

@6:40
I teach English in Japan, and a lot of my students are businessmen who have to give presentations. I always teach this distinction to avoid being deceptive, or just blatantly wrong. The way I say it is this: 5%--->10% should be said as "Increased by 5 percentage points" or "Increased from 5% to 10%". There's absolutely no ambiguity that way.
That's honestly the way I was thinking about it as well. That is, there's needless ambiguity caused by the language used in those phrases. Of course, if your intent is to sensationalize the event you'd always pick the "increase by 100%" line. Regardless, since there is no real difference between the two assertions, it comes down to semantics.
Actually, saying that it increased by 5 percentage points can be misleading. For example,to me, the pill example he gave was totally justified. Nobody cares about by how many percentage points it increased, they want to know how likely it is that they would die. And here, they would be 2 times more likely, which is extremely concerning
@@samylemzaoui2298 I'm sorry? A 200% increase isn't concerning at all, if the original death rate was 0.01%. That would mean I now have 0.02% chance of blood clots instead, which is an increase of 0.01 percentage points, which is much more honest than saying "by a 100%"
The one showing you how much more likely you are at dying is the percentage point one. Because double nothing is still nothing.
Let's say you're 10 times more likely to get hit by lightning if you're holding an umbrella. Does that dissuade you from ever holding umbrellas? No, because you know the original chance was slim already.
Hope you get it, now. Cheers!
@Salah Eddine H Yes but if the old pill has a 1/7000 chance of causing blood clots, and the newer pill increases that chance by 100%. The odds are now 1/3500. Putting it this way the odds seem significantly more likely. Or perhaps this is just another way statistics lie.
@@SalahEddineH but saying "increased by 0.01"makes it seem like it's the same as before when the product is litterally two times more likely to kill you than the last one. To me, a 0.01 percentage point increase is not as important depending on the original value, but saying that it doubled is as important no matter the scale. I don't really see how .01 is the best indicator of how much more likely you are to die like what conclusion can you draw from that as a non-statistician ? And btw i would never use an umbrella if there's a lot of thunder for this very reason
Statistical probability should never be allowed in court. It has no bearing on anyone’s guilt or innocence. That is why we use witnesses or physical evidence. Great job my hillbilly friend.
Witnesses aren't the most trustworthy source either
@@PeataPoeet But they can be cross examined to see if their story holds up.
Eyewitness testimony is, over all, is, far and away, the least reliable generally presented in criminal cases.
yeah I think that it's now no longer allowed in court. There are so many ways to make it look like one thing and be a totally different thing. The more qualities you rack up, the less likely a specific person in a group is to match that description, but it still doesn't prove it *was* them, it proves it's unlikely it wasn't them. It feels dirty to put someone behind bars not because someone saw them do it, finger prints were found and they had intent to do it, but because it's unlikely that anyone else fitting the description of the eye witness(s) exists in that city. I feel like it goes against the "innocent until proven guilty" rule of the courts.

Very very good video. It’s so important to understand statistics today. In the workplace. In the news (especially the way media reports covid stats). A constant tactic of news is to say the such and such has doubled or gone up 3 times without stating the denominator. Correlation is another common tactic I see in the workplace and in the news.
No way! I used to watch your force arena videos but I completely forgot until now
i see you comment on a lot of videos but you dont upload anymore?

Clearly you don't understand statistics. Look at the raw numbers and per capita killers anually. Covid is #1
@Basically Al Capone in legal Look, this isn't basic intuition. not everything is JUST correlation either. You need to learn a p value and a hazard ratio, and learn to read a forest plot. stats arent this easily understood and people overcorrect, thinking EVERYthing under correlation is just that. No, there is a point where the chance of correlatiom is lower and lower and thus incresing chances of causation, especially with multiple explanations. This would be like observing the sun has gone up every morning for the past 2000 years. we don't know it will go up tomorrow, but it becomes so statistically impossible for it to not go up tomorrow, plus the use of astrophysic calculations, that it is "causation". in reality, everything is just a correlation we arbitrarily bump into the causation category until a better answer is found. This is typically based on the effect on humans. One of these examples would be chances of lung cancer from smoking. It's technically not causal, but do it enough in a population, and someone will invariably get it 100% of the time.
@@jenm1 If you look at the total deaths in the US compared to the last 5 years you find something weird. They have not significantly risen this year. Then look at deaths by cause in the US for the last 5 years. You will find that they are remarkably consistent up until 2020 when deaths by covid suddenly rise AND deaths from heart disease, cancer, influenza, ect. suddenly fall. So we must consider if something about covid or the circumstances around it is simultaneously good for heart disease, cancer, AND a large number of other causes of death or if (due to financially incentivizing hospitals for covid) we are massively misreporting deaths as caused by covid. Look at the context of the numbers. Not just the raw data. I wish you well.

The whole time I was thinking how the first few court examples given must be wrong... happy you were able to share the correct interpretations later
Not really sure if its true, but i heard a story that after the British army started issuing helmets to their soldiers in WW1, they saw an increase in head injures and so people thought that the soldiers having helmets made them take more risks or get injured more. In reality a statistics person looked at it and realized people were getting more head injuries because more people where surviving hits to the head by shrapnel.
I've heard a story like that, and a similar story about airplanes, where all the ones that came back from war were damaged in certain places like the wings and other non-essential places.
the wings are non-essential?!
couldn't that cause the entire craft to lose control or even crash if the wings were damaged enough?
@@ETXAlienRobot201 I'm not sure if ww2 bomber were made like this, but the close air support a10 thunderbolt was made so it can fly with half of its wings, also a lot of the bomber wings were probably empty space where bullets and flak just went right through, with some control lines for the flaps.
true...
still, losing wings wouldn't be the best thing to do, they are there for a reason...lol
also, this would depend on the craft, if the ENGINES are mounted on the wings, well...
you would then have fuel leaks and engine failure to deal with, potentially
losing the flaps or control lines for them probably wouldn't be ideal
would also depend on the amount of damage received to the wings (or any other part, for that matter)
for all the planes that came back, how many didn't?
of the ones that did not return, WHY?
there are questions here not being asked, which also is were i was going at.
every single part of a plane is pretty essential, some might be more expendable, but i don't think a plane whose wings resemble swiss cheese is going to have an easy landing/flight.
probably the safest part to lose would be the landing gear or the weapons.
ofc, in a fight, losing guns/ammo/etc... isn't ideal, and landing gear still exists for a reason, so landing would be EXTREMELY difficult/dangerous. also, it's more likely to just fail or break during take-off, anyways. not much reason to target it when you could target wings/fuel/props to potentially cause the craft to lose control/thrust or explode/burn.
and yet another question to be asked, how many craft had to abandon their mission because of damage sustained during battle? While in the long term, having survivors might be a good thing, how many of those who survived survived at least in part because of a retreat or rescue? In the short term, both of these are a defeat. They tend to represent missions that fail or barely succeed with high casualties.
Let's just look at bombers. After a war, sure, you can just brag or state about the kinds of damages that they can sustain before crashing. (yet an additional statistic : the pilots, themselves. a less experienced pilot might be more likely to crash from minor damage to his craft than an experienced one whom could easily land/fly with half the wings missing, maybe even a failed/damaged control line or flap) Or instead, maybe you should look at:
of all the bombers commissioned and launched, how many survived?
of all the missions that took place, how many succeeded?
how many bombs actually hit their exact targets?
did any bombs not perform properly?
how many casualties per mission, successful or not?
were any of the targeted regions/countries more difficult to attack?
As this video says, statistics easily miss-lead. If the article merely mentions surviving planes, then... Can't say I'm impressed. That just says some (in the unlikely event, all) of the craft survived. It doesn't speak for their effectiveness in what they were set-out to do, or how many planes did NOT survive. That's more important than counting bullet holes and plotting locations. Due to modern medicine, you could survive many previously life-threatening stabbing/shooting injuries. Possibly without a permanent disability. (besides PTSD) It's be easy to skew this as (just making some number up as an example) "40% of people shot in the chest survive" This would discount medical care, time of response, individual fitness/health, preparedness for a bullet to the chest, etc.... It also discounts what part of the chest was shot. being shot straight in the heart would be considerably worse than being shot in a single lung. Wouldn't be surprising to see higher death rates for taking a bullet to he heart, and probably the majority of fatal chest-shots being to the heart. Oh, and just thought of these: How many bullets were fired? What were the bullets made of? Were the bullets specialized in some way to cause more damage? And when you combine all these facts, the supposed "40% survival rate" of being shot in the chest" takes *several* bullets to the chest.
If some bullets hit your wing, you can keep flying. It wouldn’t cause the wing to fall off. In the engine, just one bullet could damage a key piece of the engine, making you lose control of the plane
9:00 I had a lit math teacher and he was teaching us about this stuff. He said there was a study where, when the math teacher smiled a ton, his students ended up having better grades. There was correlation. But it was the other way around. The teacher was smiling because his class was doing well
It's important to look at cause and effect!
That may be true in that case, although I doubt it because it would more likely be a feedback loop where both factors are influencing each other. Say the teacher started the school year just after attending the funeral of his mother. His students go from a C average to a B average in the first month. Did the teacher's mood change because he successfully grieved his mother's passing or because his students are getting better grades?
correlation is not causation.

@@JonathanLyons7 "a randomly selected person " is the most common value, also known as Mode.

This is actually a very touching and interesting video. Dropping off a comment to let you know that your video made its way to my graduate school class discussion. Cheers!
100 percent of all air breathers die
conclution: dont breath
sounds like a plan
100 percent of all non-air-breathers also die.
@@ivystarlight17 conclusion: breathe
@@ivystarlight17 this is because 100% of people who have drank water die.
Conclusion: don't breathe or drink water
1 out of every 10 individuals can't spell
Conclusion: You should learn to spell conclusion and not conclution
PS. Its a joke don't get angry!
Birthdays are healthy: the more you have of them, the older you will get
Birthdays are unhealthy. The more you have the closer you are to dying.
Agent J yes, lets measure the worth of a life by counting the number of birthdays celebrated.
and what feelesh meant was that the same data looks very different if viewed thru a different lens
@Agent J you can't remember if you're dead (The dark humor has gotten to me)

@@aligator7181 ?
@@aligator7181 You can divide the fraction itself. If you don't convert it into decimal you should be fine. Do you know a way that 1/3 could actually be divided exactly using numbers and symbols that represent actual mathematics vs those that simply show that it divides in a certain way. (sorry if the way I phrased this is wonky. It's 2am here.)
@El Caranaoi
Aren't Mark Twain's quotes just the best?
@@aligator7181 your logic is like a flatearthbeliver's XD
Amusing bytheway, no bad meaning. I really enjoyed to read your words.
If u cut something into half and isn't a very same any kind of amount after, u was not cut it half. Simple like that. The problem is that u major to human imperfection. Should not. 0.3333 (3 to infinitive) * 3 = 1
Your calculator knows that. There is a video about at Veritasium chanel in some math theme one
@@aligator7181 and u keep on major to human imperfection... ;)
How can your calculator give a correct answer?
Two steps to check it
1. 1/3
2. Result * 3
Result? 1
Just because we can't do something it doesn't mean it's impossible
I gave a source
Check it out
Well explained by competent ppl
I save some time and search the exact name of the video, sec
When I taught college-level statistics back in the 80s, I had one class session titled "How to lie with statistics" that went into examples just like these of exactly how people would try to mislead them with improperly used statistics. One of the other ones I covered was color scale manipulation with "heatmap" style graphs that use colors to indicate values. For example, a graph showing temperatures can influence what you think is "hot" or "cold" just based on what temperature is chosen as the midpoint of the red-blue transition. Or, two graphs can be shown side-by-side that have different color scales to make similar patterns look different, or vice-versa.
I really thought he said “headlights” the whole time until he said head lice-

Imagine when you have a fever your headlights move elsewhere 🤣
at first i thought 'okay, maybe that makes sense since presumably the people who use headlights more than people who don't are less likely to be in car crashes, and that would affect their 'health' but nah, i'm just dumb.

I've been working on making a video on this exact topic. Tonight this video showed up in my feed.
You win again algorithm.
Before making a video always search for it
@Basics Explained, H3Vtux Your channel is fantastic as well
Seems like time has become ripe to make a video on the exact opposite thing. That people who know stuff can and does mislead with anything, not just statistics. But it's impossible to find out the truth without it, just as it's impossible to find out the disease without a proper medical test.

During WWII, the US government had research done on what parts of aircraft were most often damaged by enemy fire, to see if they could reduce aircraft loses by armoring those areas.
After research was done, they had a list of aircraft parts that should be upgraded, but a senior official informed them that their research was done incorrectly, in that it counted what parts were found damaged on aircraft that made it back to base.
He suggested that instead they should see what parts of aircraft were least often damaged on any aircraft that returned from missions, and to assume that aircraft which took damage to those areas had little chance of survival. So for example, lots of aircraft that survived missions came back with holes in their wings or fuselage, but very few aircraft that were hit in the engines or cockpits survived.
Josias von Leiswolf It was the RAF actually, the British airforce
thats pretty smart. i would have never come to such a conclusion
Shows that the method of the study is generally far more important than the results. Unfortunately, when we interpret studies we just read the results and try to assume the methods from those. I.e, results show that pets wrapped in wool blankets out-lived their naked counterparts by almost 4 years. Conclusion, wrap your pets in wool blankets. Methods: "50 household pets were held in a freezer at -20C for 5 years..."
@@gorkyd7912 That makes sense. Otherwise, people would be wrapping their pets in wool blankets with no real idea as to why. :D
I'm still trying to process the wording. I just don't get it.
Great video. I unfortunately know a lot of people who need to see this information, yet still argue statistics in ways that favor their own beliefs instead of challenge them. It’s frustrating for sure.
I wish watching this video was a prerequisite before being allowed to comment on social media articles.
i wish every news media made this video compulsory to all of its new interns. and maybe make them rewatch them twice a year just for good measure
Absolutely right. To many correlations taken as causation by the media.
And any politician or any voter
When you see a vid talking about covid you always see a panel with "check my official version of it.com*" but when there are stats in news etc there is no panel for "watch our for the stastics way of usage and their real meaning" xdddd
Stuff like this needs to be taught more regularly in schools
Statistics was a class offered in my highschool
Everyone hated the statistics class my school offered
I believe the real solution isnt teaching more about statistics, since I doubt anyone in my class learned anything meaningful. Instead, it's how the subject matter is being taught. If everything in school was taught in the same manner as this video then I'm sure students would be learning much more
this stuff is taught in math 9 in canada
Isnt it normal to study graphs and stats in high school?
I've worked on Wall Street and in military recruiting. Those positions exposed me to the world of data manipulation on a level that most would never comprehend. The tools/software available to entities that monitor us will blow your mind.
The concept doesn't surprise me, but I'm sure how accurate and pervasive it is would indeed blow my mind.
Could you suggest any resources for a simple mortal to know more???
@@amnbvcxz8650 not precisely on topic but look up Allen Dulles, the deception has been mind boggling for a long time
Would it be too scary to learn germ theory relies on statistics manipulation? The entirety of modern medicine (germ theory) rests upon correlation of data, and never direct experiments.
Exactly! So why do you think there was such a push for electronic medical records? Retired RN who also worked a few years in IT supporting several EMR’s. Also wrote reports to farm data from these and then sent my “ raw” data to quality assurance dept so they could “ scrub” it to them report out to others. I had to tag data elements in the system in order for that to show on the reports. How I tagged it and how I wrote the report and then how they merged my data w other systems reports made the final reports. So….. do I believe all of this COVID data from hospitals?? 😂😂😂
