This is video is incredible. Absolutely incredible. You made such a well done video in such a small amount of time when my many uni lectures couldn't explain anything. it just blows my mind how clear it is to me now.
Thank you for this informative explanation. I have a question thought, at 1:10 you said the distribution of the means of the random samples will be as same as the distribution of the original dataset! What if the original dataset is skewed or uniform or anything rather than a normally distributed dataset? Does this mean that the distribution of the means of random samples will be also skewed? Isn't that the opposite of what the theorem state?
IF the underlying population distribution is NOT NORMAL, and we have samples less than 30. Let's say the samples are size n = 5. I know the distribution of the sample means will not be normal according to the CLT. However, will the distribution have the same mean as the population mean, and will the variance be equal to the variance of the population divided by 5? Please let me know? thanks?
I understand that the sample size matter (ex.more than 25). But does the number of random matter? Would it work if it’s less than 30 which is presented?
It's the minimum amount for it to be graphically presented as normally distributed. Too little and you will not see it clearly, yet the theorem still applies, just that it won't be as convincing as a sample size bigger than 30.
I guess one thing the Academy should mention is k. If n is at least 25 so what about k? The true N here should be n times k in the video. It confuses people. Poor work.
Can professors stop trying to do their own awful videos and just link us to the simple explanations. Why should we waste hours when something can be explained in 4 minutes?

Brief and to the point. Loved it
This 4 min video beats all other videos out of the park! Finally I understood. So simple, yet great. Have a like

Glad you enjoyed it!
1:32 Haha, that's one hell of a variance
You sound like Dana Carvey,Love it🤗🤗
does anyone notice at 1:42 each column only has 24 numbers instead of 25?
What is the use of Central Limit theorem in machine learning? How and why should i use it on the datasets?

Sir, for getting Normal Distribution, need to increase number of samples drawn from population or the size of the samples?
Does this also assume that the sample data can be normally distributed? Since always we will be dealing with Sample data?
Complete explanation in three minutes
Super 🙏🏾🙏🏾
this is the best lecture in the world
Great video as always!!! Thank you!!

I don’t even like stats but I enjoyed this video
So happy to hear it! Thank you!

Normal uniform exponential binomial
you should replace the lecture in udemy course with this wonderful lecture or add it the course
Thank you very much
Who would dislike this video?
Your voice sounds like a 25 year old Donald Trump

makes more sense, thanks
Thank you for making this quick.
I though total sample size n is 30? 25 is just the number Of observation in each sample?
true. I thought it's 30.
Very informative video
Thank you 🙏🏽
thank u, so hellpful
I liked this one way better than Khan Academy's explanation
Could you please explain how come the variance is so big? 82k in the population? When all the numbers are lower than 1000

Thank you for such a nice so this video
We're happy you liked it!
Great video, please organize the follow-up video in playlist so we can watch next!
Thank you..was struggling with this concept…
clear and simple
Thank you
Super Duper!
This video is oversimplistic.
It’s perfect for an introduction for the subject, stfu
