17. Post hoc tests--$100 • k must be at least ___ in order for post hoc tests to be necessary. • answer

18. Post hoc tests--$200 • These comparisons directly follow from the research hypothesis and are usually few in number, so no special precautions are required. • answer

19. Post hoc tests--$300 • This is approximately equal to • # of comparisons X alpha per comparison. • answer

20. Post hoc tests--$400 • This procedure defines the minimum mean difference required for significance and can be used with all possible pairwise comparisons. • answer

21. Post hoc tests--$500 • A post-hoc test for planned comparisons that divides experimentwise alpha equally among the planned comparisons, resulting in a more stringent critical value for each of the comparisons. • answer
