Both a t-test and ANOVA compare group means. A t-test is used when determining if two means (i.e., averages) are the same or different. An analysis of variance (ANOVA) is performed when comparing three or more means. The procedure of calculating a series of t ratios involves a great deal of work and increases the probability of making a ...
