Question
When would you use Tukeys?Select one:a.To follow up Friedmansb.As post hoc tests for an unrelated ANOVAc.To compare two groupsd.As post hoc tests for a related ANOVA
Solution
You would use Tukey's test as a post hoc test for an unrelated ANOVA. This test is used when you have three or more groups and you want to compare every group to every other group to find out which ones are significantly different from each other. It is used after an ANOVA when you have a significant result and you want to know which groups were significantly different from each other.
