WebFeb 16, 2024 · The formula for a Bonferroni Correction is as follows: αnew = αoriginal / n. where: αoriginal: The original α level. n: The total number of comparisons or tests being performed. For example, if we perform three statistical tests at once and wish to use α = .05 for each test, the Bonferroni Correction tell us that we should use αnew = .01667. WebJul 14, 2024 · Although the Bonferroni correction is the simplest adjustment out there, it’s not usually the best one to use. One method that is often used instead is the Holm correction (Holm 1979). The idea behind the Holm correction is to pretend that you’re doing the tests sequentially; starting with the smallest (raw) p-value and moving onto the …
