When I run a 1 way anova, most of the time I do not have the Posthoc/multiple comparisons tab available (it is greyed out). I can't figure out what is causing this. I have checked the obvious things (e.g. my column counts are equal for group names and data, I have no missing or weird data). Any ideas?
You seem to have CSS turned off.
Please don't fill out this field.
the Toolbox will not allow you to perform posthoc tests if there is not a significant difference in the ANOVA, i.e. if p > 0.05.
Duh! Thank you!
