This video gives you a taste of just how laborious, tedious, and annoying statistics can be -- but also how easy calculators make stats -- by introducing you to one of the larger square root equations you'll ever see. I mean seriously, sigma notation INSIDE of a giant square root, with BOTH i's and n's... It doesn't get better than that!

Standard Deviation & Normal Distributions

This video takes a more conceptual stab at standard deviation by showing you what's at the heart of Statistics: the "normal distribution". Also covered, perhaps the only thing you'll remember about Stats in 5 years: the 68-95-99.7 Rule.
