Tukey's Studentized Range (HSD) Test for IMC

Note:

This test controls the Type I experimentwise error rate, but it generally has a higher Type II error rate than REGWQ.

Alpha	0.05
Error Degrees of Freedom	12
Error Mean Square	1.382708
Critical Value of Studentized Range	4.19851
Minimum Significant Difference	2.4685

Means with the same letter are not significantly different.
