Abstract

SCHULZ (1976) gave formulas for the approximate computation of the percentage points needed for the comparison of sample means by the Maximum‐Modulus‐Test resp. by the DUNNETT‐Test. Our investigation shows that these formulas are also practicable if the number of the mean differences k is greater than 20. The maximum difference between the exact values and the approximate values of the percentage points amounts to 0,05 in the case of the Maximum‐Modulus‐Test with k >20 and degrees of freedom v > k for a level of error a = 0,05 resp. a = 0,01. In the case of the DUNNETT‐Test this maximum difference amounts to 0,02 for 20 < k < 50 and a = 0,05. Besides it can be here supposed that the approximate percentage points are also practicable for both k >50, a = 0,05 and k >20, a = 0,01.
