George Carlin — Stupider than Average

George Carlin makes a simple statistical error (unless he’s talking about a symmetric distribution) in describing the intelligence of the average person. Typically, the measure he is describing refers to the median, which would place half of the sample above the value and half the value below. Many students assume that the median and the mean are the same thing and will often describe them similarly, but averages can be prone to outliers. In this case, a really dumb person in a room full of genius can pull the average way down, but won’t change the median.
