The average point is the mean…And the mid-point is the median. Average doesn't need to fall at the mid-point, and more often than not, it doesn't. Here's a group of numbers: 10, 10, 8, 6, 3, 2, 2, 2, 1. The median (mid-point) is 3; the mean (average) is 4.9. I can't speak to defense. But I believe it was Bill James who pointed out that on offense, there are more below average players than above. That means that an average offensive player would likely fall into the top half rather than just being ho hum. But how will Chris Carpenter explain this to his son?
