Abstract
When the F-ratio determined by analysis of variance indicates a significant difference between sample means, it is desirable to determine which means are significantly different. The Newman-Keuls test (Procedure 36) is applicable for this purpose. When the sample sizes are equal, additional tests (besides Newman-Keuls) may be used. We discuss here one such test based on calculation of a quantity representing the smallest difference which could exist between two sample means if these means are significantly different. In Procedure 37 we presented an alternative test (Duncan’s). Neither of these tests should be applied if the F-value (Procedure 33) does not indicate a significant difference.
