WebFamily-wise error rates Other FWER-controlling procedures FWER The family-wise error rate (FWER) is de ned as the probability of making at least one false rejection in a family … WebIn the first step, all null hypotheses in the family are tested with a single, omnibus test, such as the F-test in the one-way ANOVA setup. If this test does not reject the overall null hypothesis at level α, then stop. If it does reject, then proceed to the second step: Carry out individual tests for the family of comparisons, each at level α.
