WebExample 3.3: Tukey vs. Bonferroni approaches. Here is an example we can work out. Let's say we have 5 means, so a = 5, we will let α = 0.05, and the total number of observations N = 35, so each group has seven observations and df = 30. If we look at the studentized range distribution for 5, 30 degrees of freedom, we find a critical value of 4.11.
