After ANOVA, assume that we want to do all of the pairwise comparisons between the means in this case. Tukey Pairwise Comparisons: Grouping Information Using the Tukey Method and 95% Confidence Factor N Mean Grouping dept 3 6 5120 A dept 2 6 3755 A dept 16 1536 B Means that do not share a letter are significantly different. Using the Tukey Table above, describe what you learned about the pairwise comparisons between means. O mean dept 1 not = mean dept 3 O mean dept 2 not = mean dept 3 O all means are different O mean dept 1 not = mean dept 2 %3D

We asked UST employees to tell us how many megabytes of memory (RAM) they have on their computer. We would like to test to see if the mean amount of memory is the same for three different academic departments. We have the memory amounts for six faculty members' machines in the three departments shown below.
