Thank you so much! Exams in a few days and I never learned those Position formulas!
Good luck on your exam! I hope it goes well :)
Please make a video on Hypothesis testing with the usage of different tests based on the type of data. Thanks in advance
Nice its needed in data mining and data warehousing Thank you
Thank youuu!!
Very helpful!!!!
Thank you! I saw a tutorial in which he calculated the IQR and 5 number summary without including the outlier in the dataset
Excellent
thanks a lot!
Good Job 👍
it was very helpful
Thanks so much for your efforts
And thank you for watching!
Thank you
OMG THX SOME MUCH!!!! U SAVED A LIFE
WOO HOO!!! GLAD I COULD HELP :)
Perfect!

THANK YOU SO MUCH.
#OnlineSchool
Very effective
great presentation. what animation software did you use to make this presentation
thank you
Please make video on chi square and other tests
Working on it :)
@@Simplelearningpro oh thanks so much
Hi, Simple Learning Pro, can you please give me a few references, book or paper, of finding the outliers that you've shown in this video (Data Value < Q1 - 1.5 (IQR)....), I may need it for my research. Thanks.
that cute suited up figure is everything
I tell ya what, actually i won't tell you anything of note - awesome video
Excellent and neat ! I wan't to do like those videos for the company I work for (but Medical domain), could you please tell me the software you are using? thank you so much.
I used Microsoft power point to create the animations, and you can use any video editor to to edit the footage. Good luck!
So helpful
you cracked it in 5 minutes, while the guy in the online class took 50, thanks
Hehe thank you so much!
For identifying the outlie, why do we multiply the IQR by 1.5? The 1.5 what does it mean?
Why do my book complicates this easy concept...
Thanks for the video , it is really helpful>
So both the modified and original box plots use the same five number summary?
does it matter if the numbers that you are given are already in least to greatest order, and if they're not do you put them in that order and than do the calculations?
Yes that is correct! And if the numbers are already in least to greatest in order, that just saves you a bit of time :)
👏
In this example you are talking about a single outlier, but what happens when you apply the formula and it turns out that you have a significant amount (for example, more than 15%) of outliers?
Hey great question. After making the necessary calculations and it turns out that you have more than one outlier, it is very possible and normal!
Can you plz tell me what's the physical significance of an outlier data?
An outlier can skew statistical results. For example, if you had a random sample size of 50 and wanted to calculate the average income within that group, if Bill Gates happened to be in your sample, the average income would be over-estimated due to the presence of Bill Gates being in the sample. To put this in perspective, Bill Gates makes about 4 billion per year, whereas the average salary in the US is about $30,000 USD. Bill Gates makes more than the entire sample size combined... times over 2000, which is HUGE!
@@Simplelearningpro
Got it, Thanku so much..!!!
What is use of the outliers? And
Where we use
Outliers are those value which cause us to get different result than usual, if present they should be avoided.
why oh why does this channel has only 112k subscribers..................
seen
What if I have 14 data value, so how do I find the MEDIAN #? I'm a bit lost here.
At 3:45 how can this be visualized?
im fucking spamming likes on all of your videos bc is helping me so much srsly
Thank you so much it has been helping!
Why we didn't use quartiles formulas??
Is spread IQR or Range? I'm confused
Is anyone not gonna mention the equations of the outliers. If you do the Q1 equation you get -8.5 which he didn't mention at all.. I tried the equation on my own problem and the number was extreme. I don't get it.
What is N+1 / 2,
That is the formula that will help you find either the median, Q1, or Q3
🤩👍👍
Q1 - 1.5(IQR)...... can you pls explain why you'r multiplying with 1.5 ?
That is just the standard formula that they teach in introductory university statistics. They chose the multiplier 1.5 because statisticians found that it works the best. The reasons why they chose 1.5 go more into complicated detail but it is not necessary to know for introductory statistics. If you are curious, there are many explanations you can find on google :) So for now, I wouldn't worry about it too much! I hope that helps.
@@Simplelearningpro Thank you for explaining and you'r statistics 1 series is very helpful :)
@@vikasvk9174 Thank you :)
It’s the dream of math! Lol
POV: your teacher gave you this, but instead of paying attention you're in the comments
Why it is only 1.5 ? Not 1.4 or 1.6 ?
Great question! I myself do not know the answer to this, I guess that is just the number that statisticians agreed upon.
@@Simplelearningpro Great!!!
Why 1.5 factor*(IQR )?
That is a commonly used rule to help identify outliers
@@Simplelearningpro But why? Why 1.5 only? Why not other ?
@@lokeshshingadi 3/2 works as well, 6/4, 12/8, 150/100
@@haydenmorris9608 😑😑😑 all are same
@@lokeshshingadi 1.5 is a formula of the IQR
