this is kind of late but I was wondering how you got the standard deviation of baby height measurement is +/- 1.2 vs the standard deviation of adult heights of 8? How did we get the value of 1.2 and 8? I am not sure if I used the correct wording or if what I am asking make's sense but hope I can get an answer!
@@santiagoramos1313 I just googled "average adult height" and found a table that listed the mean and standard deviation for the world and individual countries. I then did the same thing for babies. In other words, I didn't calculate those values, I just looked them up in a table.
@@kartikaykhattar96 I believe yes as there are only 2 possible outcomes. However if the question is something like percentage understanding or confidence level in percentage it will likely be normally distributed.
These unexpected silly songs really relieve the pressure before getting into the subject. They are an integral part of the Statquest pedagogy, they act as a mind-opener :)))
dude, you make my day. every time I watch one of your vids I am usually super stressed bc our prof doesn't take the time to explain a darn thing. thanks a lot for making this free and enjoyable
Luckily this video popped out in the beginning of my search list ! Such a clear explanation about Normal distribution that I was struggling to understand since years!
These videos are literally amazing, every single one is so clear and well presented and the use of visuals is top notch. Can't wait for the central limit theorem one!
this is an extremely precious channel whoever wants to start with stats... Thank you so much for making people's life easy by this channel. N, of course, the starting songs are really congenial.
wow this is so much easier to understand then my dense obtuse intro to stats textbook!! thank you so much, i had no idea what they were talking about in that dang book
One Word! Simply Awesome. After 40 yrs of coming on this earth, today I understood normal distribution and standard deviation. Have been ignoring it since long to understand. Thank you.
Did a Google search for the best youtube channels to learn basic stats. I am so glad i found your channel. I am doing a final year of my bachelor and I am doing an online stats course which is not easy to understand. I find that I can "just get by" on the quizes and assignments but I am not really understanding the material. I don't want to just pass, I want to be able to apply stats in business problems (I am a mature student...meaning I am old). Your channel is helping me truly understand stats. Thank You
Clear and simple explanation. As most things are in the world. There is not complex or heavy themes or things. There is just people that do not know how to explain it because they do not understand them. I used this explanation for understanding limit of detection in analytical measurements. Thank you
Thank you so much for this. I spent a good hour re-reading the subchapter on gaussian distribution in my university textbook and I just could not wrap my head around it. This video made it so simple and it has finally "clicked" in my tired, frustrated brain. Very much appreciated
I completely agree with Em c!!! I am struggling and after a year, I found your video! For the first time, my head didn't hurt!!! Great, detailed instructional videos!!! Thank you
I subscribed halfway through the intro. when you know, you know. Edit> I just watched the entire video, it's brilliant. A wonderfully concise overview of the subject. I'm always looking for videos like these to give me the core explanation that I can hang the details on to as I go. 5 minutes to explain what it takes a textbook 50 pages. I can't wait to watch the next video on the central limit theory. Thank you Josh great video.
@@statquest BAM! I just finished my exam today. Your videos are super helpful and also fun. Now I don't watch them for the sake of exams just simply for fun.
I liked the explanation. Just one small thing i would like to add which many people might overlook. In real life situations, we do not draw the curve such that its width is defined by the std dev. Its the other way around. Like we just have data points from which we plot the curve. Then if its a curve satisfying these parameters discussed in the vid, we named it normal disrtibution. So , for example "Peak of the curve is given by avg" is not same as "peak of the curve happens to be the avg". Idk if i explained it properly but i jusy wanted to point out that the bell curve is not bound to follow these avg and std dev values, more like in this case of disrtibution, which we call as normal, the avg, std dev etc values fall in such that, say 95% of data is inside avg +- sigma width.
Strange that we have to look for online resources like this one to try to make sense of normal distribution after we have signed up for a paid course thats supposed to teach us the concept. Lecturers and course material just assume most people know distribution at a certain level.
Its super super exciting to watch your video ,you are doing great job i always had fear of learning statistics but you explained in a very simple way,,Thank you You are awesome
I get teachers like to explain how this works as it is said on the syllabuses but as a person who has not heard of this i wouldn't understand anything, they should just explain it like this because now i know how to read a normal distribution graph and how to write one as well, thank you :)
Wow, I like you. I just like you. 2 days of trying to understand normal Distribution!! You killed it in less than 5mins. Give me more with practical examples. 🤓
Short videos like these are awesome to rewatch when you understand concepts which build on them :). Reminds you of all the little things to more easily grasp concepts later on!
I think that if you really want to be good at ML, you need to understand data, and the normal distribution is one of the most fundamental concepts for understanding data.
Hi, great videos for basic conceptual understanding. Can you make one about z-scores? I want to understand how the values are scaled, I think it does it across variables to account for differences in units.. but that stumps me up! Can you explain when to use it and when not to? Or any links where bloggers/ youtubers have already explained this properly 😅
Your videos are great. I am a professor and I learn a lot from your videos!! Can you please do videos in these topics : - partial least squares - metagenomics data analysis Thanks in advance
Learnings: 1. Normal Distributions are always centered around mean. 2. Normal curves are drawn such that 95% of the measurements fall between +/- 2 Standard Deviations about mean. 3. To draw a normal distribution you need mean and standard deviation

why is the standard deviation of babies is .6 and 4 for the adults ? thank you fir your time
Because there is much less variation in how tall babies are compared to adults.
