General Linear Models Procedure
Sidak T tests for variable: SCORE
NOTE: This test controls the type I experimentwise error rate, but
generally has a higher type II error rate than REGWQ.
Alpha= 0.05 df= 28 MSE= 2.178571
Critical Value of T= 2.83
Minimum Significant Difference= 2.0886
Means with the same letter are not significantly different.
