WebFalse Discovery Rate. The false discovery rate (FDR) is a less conservative approach to multiple comparisons correction than the traditional methods described earlier.

Prism then tells you which P values are low enough to be called a "discovery", with the goal of ensuring that no more than Q% of those "discoveries" are actually false positives.

When you perform a large number of statistical tests, some will have P values less than 0.05 purely by chance, even if all your null hypotheses are really true.
