Abstract
Abstract Type I error and power rates for pairwise comparisons of means were obtained from a Monte Carlo investigation of the Gabriel (1978) and Hochberg (1974) multiple comparison procedures (MCP's). This addendum to the Keselman and Rogan (1978) study indicates that MCP's that obtain a standard error of the comparison using a pooled within-cell estimate of error variance cannot maintain the overall Type I error rate at α when the largest of a set of unequal variances is paired with the smallest of a set of unequal sample sizes and vice versa. Two procedures for computing pairwise multiple comparisons are recommended.
