WebbThe Critical-Value is 3.413 Why are we choosing .95 as our quantile and not .975? The Tukey distribution only looks at the SIZE of the differences between means, not their direction. That's why it's always positive. Therefore, the choice of quantile (.95) it justified by the fact that the Tukey test is one-sided. WebbIn the Tukey procedure, we compute a "yardstick" value ( w) based on the M S Error and the number of means being compared. If any two means differ by more than the Tukey w value, then we conclude they are significantly different. Step 1: Compute Tukey’s w value w = q α ( p, d f E r r o r) ⋅ s Y ¯
