He is a wonderful teacher who tries his best to clarify for his students what is abundantly crystal clear to him. He also seems to love what he does and that is contagious.
camera guy; I like your work however I find it hard to follow the prof. if you dont follow him, since this video is on youtube I can pause and rewind if I need to
You are correct! for sample correlation coefficient, it should be divided by n-1 not n. I think he is wrong here. Interestingly, if I give you a list of order pairs without telling you if they are the whole population or they are just a sample. You go ahead and calculate sample correlation coefficient (divide by n-1) and then calculate the population correlation coefficient (divide by n). You will see in either case you will get the same result.

I see what you did...why use a nonstandard definition of the sd?

Why is the division by n and not
(n-1) for the sample correlation coefficient?
