When to use Post hoc comparisons - ️️You would use post-hoc comparisons when the overall F statistic was significant, but you did not make specific predictions beforehand about the nature of this difference. When to use power analysis - ️️Power analysis is used when we want to know how sensitive our study is in terms of being able to detect effects. Power is therefore the probability of that a sample will yield statistically significant results when a mean difference truly exists i...

ANOVA UPDATED Exam Questions and CORRECT Answers What is an ANOVA? - Correct Answer- ANOVA is an analysis of variance between groups (or levels of a factor) or within groups (or error) Whereas t-tests compare only two sample distributions, ANOVA is capable of comparing many. We partition the total variance into how group means differ from the grand mean and how individual observations within groups differ from their group's mean
