The cutoff f used to evaluate the significance of the scheffé test for any particular comparison between two group means is the same cutoff f used for the overall study.
In statistics, the Scheffé method, named after the American statistician Henry Scheffé, is a method of adjusting significance levels to account for multiple comparisons in linear regression analysis.
The Scheffé test can be used to determine whether individual means differ or whether the mean he of one group differs from the mean of another group.
If you want all possible contrasts between group means, you should use the Scheffe post hoc test. Unlike the Tukey Post Hoc test, this test allows him to compare more than two means at once. Suppose he has four groups, A, B, C, and D.
