The fact that it considers more than two variables makes it different than the independent samples t-test. You use mse which measures the mean square error. You have more than two groups that you"re potentially comparing amongst. It is done instead of an anova. It is done to test a particular hypothesis that was derived prior to the data being collected. It is a planned comparison because it tests particular hypotheses. If you have a particular hypothesis in mind that doesn"t involve testing all hypotheses, the a priori t-test is more applicable.
