Tests include the T-test, the F(1-way), F(2-way with equal Sample Size), F(3-way with equal Sample Size), and the F(2-way with unequal Sample Size).
The two-sample t-test checks if two population means are equal.
The ANOVA or F test determines if significant differences exist among treatment means or interactions. It is a preliminary test that indicates if further analysis of the relationship among treatment means is warranted.
