In Figure 6.16, the Tukey-Kramer HSD Threshold matrix shows the actual absolute difference in the means minus the HSD. Pairs with a positive value are statistically significantly different at the specified alpha significance level. The q* value in the confidence quantile table represents the quantile that is used to scale the HSDs. It has a computational role comparable to the quantile in a Student’s t test.
