Block 8 Lecture - Variance

[JacobBumgarner]

On slide 15/18 of the descriptive statistics lecture from block 8, I believe that the left side of the equation for the calculation of variance is incorrect. I know this isn't a huge issue, but I wanted to point it out!

On another note, I want to thank the group for making these lectures available. This is a highly valuable resource that I've found real benefit from and have enjoyed using!

Yes, that makes sense. Thanks for reporting @JacobBumgarner ! We'll fix that during the upcoming semester.
