Abstract
Tables of sample sizes for the analysis of means necessary for detecting differences among k treatments when two of the treatment means differ by at least a specified amount Δ (measured in units of the process standard deviation) for fixed level of significance α and fixed power P are given for α = 0.1, 0.05, 0.01 P = 0.5, 0.6, 0.7, 0.75, 0.8, 0.9, 0.95, 0.99 Δ = 1, 1.25, 1.5, 1.75, 2, 2.5, 3 k = 3(1)20, 24, 30, 40, 60. A comparison of these sample sizes with previously published sample sizes for the analysis of variance does not reveal any substantial differences. Examples of the use of the tables are given.Keywords
