Median Memes

Homer Simpson's mathematical blunder is the statistical equivalent of stepping on a rake. The median of 10, 10, 20, 40, and 70 is actually 20, not 30! Poor Homer confused median with mean (average), which indeed equals 30. Sandra's withering "that was mean" punchline works on two glorious levels - condemning the correction while inadvertently naming the very statistical measure Homer should've used. It's like watching someone confidently announce that mitochondria is the powerhouse of the animal.
