When I plan a study, and I am gonna use 5 tests, I do not care about the 1 test I may be doing in 5 Years, I care about how likely is it that one of my 5 tests produces a wrong result.
WebApr 26, 2024 · To adjust for family-wise errors, there are some ways. Bonferroni suggests a simple way of dividing the p-value by the number of tests, known as Bonferroni adjustment for p-value. However, this adjustment is very conservative. In order to decrease false discoveries, it increases the chances of false negatives.
