My professor spent over an hour and a half teaching this and I was so lost. Watched this 8 minute video and it's all so clear. Fantastic work.

Thanks you sir....

[@STDrepository]

Would you recommend using what you used. o^2 = sum (x-u)^2/n
or using o^2 = sum (x-u)^2 * P(X)? is there any difference between them?

[@mzboutmabread]

Learning this online was like rocket science and I'm a student that's getting mostly A's and a B. Thank you sir for this video. I get it now

[@julianb236]

I wish you could calculate a higher sample size(maybe 12), that one is way to simplistic.
