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.

Step 3: Put the value obtained above we get Critical Range = 4.124. Step 4: Compare it with every result in Step 1 we get all of the absolute mean differences are greater than the critical range. WebbUsing Tukey's method, you specify that the entire set of comparisons should have a family error rate of 0.05 (equivalent to a 95% simultaneous confidence level). Minitab calculates that the 10 individual confidence levels need to be 99.35% in order to obtain the 95% joint confidence level.
