According to Kirk's (1995) Experimental design: Procedures for the behavioral sciences, "Scheff?'s procedure is always congruent with the omnibus F test. If the omnibus F test is significant, there is at least one contrast among the means that is significant according to Scheff?s test, and vice versa." (p. 155)
Interesting! I have a much older version of the Kirk book (from 1968, when Kirk was still commanding the Enterprise), which doesn't say that. Rick, use the Scheffe procedure to make some complex comparisons and tell us what happens! --David Epstein [EMAIL PROTECTED] --- To make changes to your subscription go to: http://acsun.frostburg.edu/cgi-bin/lyris.pl?enter=tips&text_mode=0&lang=english
