An Apple IIE microcomputer program for multiple non-independent comparisons by the Scheffe's test.

Abstract

When more than two groups of observations from the same set of experimental data are compared and pairwise tested for equality of their means, appropriate statistical treatment of the data is required. The overall variation in the set of data must be considered, and also the statistical non-independence of each pairwise comparison must be taken into account. We describe a simple Apple IIE microcomputer program that applies the Scheffe's test for multiple comparisons. A numerical example and a sample output of this program are also included. The listing of the program is reported in the Appendix.
