Computer Programs: Simultaneous Pairwise Comparison Tests Among Treatment Means

Summary: A FORTRAN computer program is presented which provides a number of test statistics and their critical values for the simultaneous pairwise comparison of several treatment means. The different test statistics are applicable in specific situations with respect to the balance in the number of observations available for each treatment mean and the consistency or homogeneity of the standard deviations for each treatment. Descriptions of the various test statistics for each situation are given and examples, illustrating the application of these statistical tests and the computer program to actual process quality data, are presented.
