The Tukey-Kramer procedure is used to make pairwise comparisons between group means after an ANOVA indicates there is a significant difference among the groups. However, it does not automatically mean that all pairs of group means are significantly different; it only tests for differences. The outcome depends on the specific data and comparisons made.
