WebMay 1, 2024 · Bonferroni Multiple Comparison Method. A Bonferroni confidence interval is computed for each pair-wise comparison. For k populations, there will be k ( k -1)/2 multiple comparisons. The confidence interval takes the form of: F o r μ 1 − μ 2: ( x 1 ¯ − x 2 ¯) ± ( B o n f e r r o n i t c r i t i c a l v a l u e) M S E n 1 + M S E n 2. WebScheffé's method for investigating all possible contrasts of the means corresponds exactly to the F -test in the following sense. If the F -test rejects the null hypothesis at level α, …
