An Empirical Investigation of Tukey's Honestly Significant Difference Test with Variance Heterogeneity and Unequal Sample Sizes, Utilizing Kramer's Procedure and the Harmonic Mean
Description:
This study sought to determine the effect upon Tukey's Honestly Significant Difference (HSD) statistic of concurrently violating the assumptions of homogeneity of variance and equal sample sizes. Two forms for the unequal sample size problem were investigated. Kramer's form and the harmonic mean approach were the two unequal sample size procedures studied. The study employed a Monte Carlo simulation procedure which varied sample sizes with a heterogeneity of variance condition. Four thousand ex…
