Family-wise inflation of error rate
WebThe Bonferroni correction adjusts the rejection threshold, so that the overall likelihood of making at least one incorrect type 1 inference (i.e. reporting an effect when there is none and committing an alpha error) remains at the chosen significance threshold (usually 5%), even when multiple hypotheses are tested within one study. WebApr 26, 2024 · So, the probability of at least one Type I error is 1 − .857 = .143, or 14.3%. Therefore, across this group of tests, the probability of making a Type I error has increased from 5% to 14.3% This error rate across statistical tests conducted on the same experimental data is known as the familywise or experiment-wise error rate.
