  author={S. Olejnik and JaeShin Lee},
ABSTRACT A review of the literature on multiple comparison procedures suggests several alternative approaches for comparing means when population variances differ. These include: (1) the approach of P. A. Games and J. F. Howell (1976); (2) C. W. Dunnett's C confidence interval (1980); lnd (3) Dunnett's T3 solution (1980). These procedures control the overall riJk of a Type I error experimentwise at approximately the nominal significance level and have the best statistical power among… CONTINUE READING
