A Power Investigation of the Tukey Multiple Comparison Statistic
Keselman, H. J.
Educational and Psychological Measurement, 36, 1, 97-104, Spr 76
Investigates the Tukey statistic for the empirical probability of a Type II error under numerous parametric specifications defined by Cohen (1969) as being representative of behavioral research data. For unequal numbers of observations per treatment group and for unequal population variancies, the Tukey test was simulated when sampling from a normal and a skewed population. (RC)
