"WebMar 24, 2016 · The Bonferroni correction is a pretty conservative approach to hypothesis testing. For n tests, it requires you a p-value of p / n where p is your significance level. This guarantees that the probability of you getting a positive by pure chance stays below p, but sometimes it makes it go way below p, thus also losing power in your tests.
