All Pairs, Tukey HSD

The All Pairs, Tukey HSD test (also called Tukey-Kramer) protects the significance tests of all combinations of pairs, and the HSD intervals become greater than the Student’s t pairwise LSDs. Graphically, the comparison circles become larger and differences are less significant.

The q statistic is calculated as q* = (1/sqrt(2)) * q where q is the required percentile of the studentized range distribution. For an example of this test, see Example of the All Pairs, Tukey HSD Test.
