The Normal Distribution, aka The Normal Curve, aka The Bell Curve, is a crucial topic in statistics. Hall of fame football mastermind John Madden (aka “Boom!”) explains how using the mean and the standard deviation of a data set reveals how well running backs perform at the NFL combine. His 2-minute drill also covers a great rule of thumb process called The Empirical Rule (68-95-99.7), which uses percentiles to help us understand how well the runners did compared to each other. Enjoy Madden’s signature drawings, right on the screen!
