What goes in the denominator of variance & standard deviation

We’ve gotten a few questions on the problem set for the central tendency and variance module, specifically what goes in the denominator. In some places it seems like we say put N in others we say put n-1. And that answer is right… but of course it’s more complicated than that.

I put an explanation within the problem set itself, so please check it out and let me know if there are any further questions.
