Statistics in perspective

Mathematics are funny:

1) Correlation and causality:

"It is proven that the celebration of birthdays is healthy. Statistics show that those people who celebrate the most birthdays become the oldest" (credited to S. den Hartog)

2) Power of arithmetics:

"A physicist, a biologist, and a statistician see two people enter a house, and then after some time, they see three people leave the house.

The physicist concludes, "My initial observation must have been incorrect." The biologist concludes, "Clearly, the two reproduced..." The statistician concludes, "Well, if one more person enters the house, then there will be no-one in the house!"

3) Bayesian flavour:

"A Bayesian is one who, vaguely expecting a horse, and catching a glimpse of a donkey, strongly believes he has seen a mule".
