## How is the Scheffe test calculated?

Step 1: Calculate the absolute values of pair wise differences between sample means. You’ll have to figure out all the possible combinations. For four samples, there are 6 possible combinations of two: AB AC AD BC BD and CD. For example, for AB the absolute difference (|A-B|) is 36.00 – 34.50 = 1.50.

#### Is the Scheffe test suitable for Post Hoc comparisons?

While pre-planned comparisons can be made using tests such as t-tests or F-tests, these tests are not suitable for post hoc or unplanned comparisons. For such comparisons, multiple comparison tests such as the Scheffé test, the Tukey-Kramer method, or the Bonferroni test are appropriate.
