multiple cells not adjacent in graphpad prism 5

If you choose to look at Simple effects (defined above), the definition of family is not obvious, and Prism offers two choices: Similarly, the confidence level (usually 95%) applies to the entire family of intervals, and the multiplicity adjusted P values adjust each P value based on the number of comparisons in a family. The significance level (alpha) applies to the entire family of comparisons. Multiple comparisons take into account the number of comparisons in the family of comparisons. How many families? (Applies to simple effects only.)

The choice should be based on experimental design and the scientific questions you are asking.

This choice is not available when one factor is repeated measures, but is available when both factors are repeated measures.ĭo you want to compare each mean (in the set) with each other mean? Or only compare each mean to the first, control, mean? The latter approach makes fewer comparisons, so has more power. Compare each cell means with every other cell mean, paying no attention to which row and column each cell mean is part of.
