Ha ha. I used to repeat the p value interpretation over and over in different ways to the class in the hopes of eventually explaining what it is not. I did dare you to wrap your head around it, so you were warned!! It is an upside down concept.

You know the value is 0.05 because fisher had a tabulation of the zeta function lying around with 0.05, 0.025, and 0.01 in it when he was writing the paper?
