If m independent comparisons are performed, the family-wise error rate (FWER), is given by Hence, unless the tests are perfectly positively dependent (i.e., identical), increases as the number of comparisons increases. If we do not assume that the comparisons are independent, then we can still say: which follows from Boole's inequality. Example: WebJ-STAGE Home
