Description
Testing the equality of several independent group means is a common statistical practice in the social sciences. The traditional analysis of variance (ANOVA) is one of the most
popular methods. However, the ANOVA F test is sensitive to violations of the homogeneity of variance assumption. Many alternative tests have been developed in response
to this problem of the F test. These tests include some modifications of the ANOVA F
test and others based on the structured means modeling technique. This paper provides
a SAS macro for testing the equality of group means using thirteen methods including
the regular ANOVA F test. In addition, this paper summarizes the results of a simulation study that compares the performance of these tests in terms of their Type I error
rate under different conditions, especially under violations of the homogeneity of variance
assumption
