Lecture 7 - The Central Limit Theorem
What does it mean to be average? Why are we so concerned with averages? Two reasons are that they give us a middle ground for comparison and they are easy to calculate. This lecture covers averages and the Central Limit Theorem which is one of the most powerful and useful ideas in all of statistics.
