An analysis of variance differs from a t test for independent means in that an analysis of variance "is usually used to compare two groups, while a t test for independent means can be used to compare two or more groups" "can be used to compare three or more groups, while a t test for independent means cannot be used to compare more than two groups." "is conducted before the experiment, while a t test for independent means is conducted after the experiment" "includes computation of group variances as part of the analysis, while a t test does not include these computations"
