p-values... Quintal

OK, the p value, or probability value, has to do with hypothesis testing. Basically, the smaller the p value, the more significant. In most sciences, .05 is pretty much the bottom end of the significant range, with p values of .01 to .001 considered pretty strong evidence. A p value of .05 means there's about a 5% probability of error.

I can't find my Stats text, but I'll look for it later and try to give a better explanation. Statistics isn't really math-like, it's much more about logic and thinking, so it's harder for me to remember or understand well enough to explain to others... Man, who knew I'd be such a dork?
