I was looking for a reference to the story about bullet holes in bomb planes, and came across this fun page on statistical lore. My favorite:
Question: How many people have more legs than the average?
Answer: Almost everyone. This is because the number of three-legged people are greatly outnumbered by one-legged people, so the mean (i.e. the posh mathematical way of saying that which most people think of as the ‘average’ [total sum divided by number of values]) number of legs is a little bit lower than 2.
I also liked the fact that, statistically speaking, there are 2 popes per square kilometer in the Vatican….
