ADEQUATE SAMPLE SIZES FOR RANDOMIZED BLOCK DESIGNS

摘要

Techniques described in an earlier report [1] are used to generate tables of sample size requirements for testing treat¬ment effects in a randomized block design. Maximum values of the standardized range of the treatment means are tabulated for k = 2(1)6 treatments;b = 2(1)5 blocks;N = 1(1) 30(2) 50(5) 100 observations per cell;and a = 0.01, 0.05 and f3 = 0.005, 0.01, 0.025, 0.05, 0.1, 0.2, 0.3, 0.4 levels of risk.
