Webb5 juni 2024 · One way to think of this: Suppose you have a bunch of tests that all have p < 0.05. The multiple comparisons make it easier to get one p -value less than 0.05, but make it harder to get all the p -values less than 0.05. No matter what the correlation between these tests, that's going to happen less than 5% of the time under the null.

WebbThe key idea is identifying significance by chance. As you increase the number of comparisons you increase the number of those that will be significant by chance. For example, let's take the generic example of doing 100 comparisons using a significance threshold of 0.05.
