Quizplus · Accepted Answer

Tukey's test is a post-hoc test that is used to determine which specific groups differ significantly from each other after finding a significant result in ANOVA. While the overall F statistic indicates that there is a significant difference somewhere among the groups, it does not tell us which specific groups differ from each other. Therefore, Tukey's test or another post-hoc test would still be needed.
