Central Limit Theorem
Intro to Central Limit Theorem
This video explains what the central limit is, and outlines how you'll be using it to solve big fancy word problems. It also shows you where that graph comes from that's in every book and lecture on the topic: a pile of sample variances, x-bars and p-hats stacked up in the shape of a normal distribution.
Rules for Central Limit Theorem
This short video explains the "criteria" for when you're allowed to use the central limit theorem. Not that you'd care, except that's often the first step of test and AP questions.
