The t test for dependent samples is used to compare the means of two related groups (e.g. same subjects tested under two different conditions). Regression is used to examine the relationship between two or more variables. Analysis of variance is used for comparing the means of more than two groups. The t test for independent samples is used to compare the means of two independent groups.
