Contrary to T-test in only two groups, ANOVA (Analysis of Variance) is commonly used technique for comparing the means of two or more groups. Multiple comparison methods are often performed following a significant finding in the ANOVA. There are a number of multiple comparison procedures in the literature. Although several methods are commonly available in statistical software packages, some researchers face difficulties in interpreting their data. In this paper, we demonstrate the differences of several methods for the treatment means using SAS program.
