Answer #1

Dear your satisfaction is more important, so I provided answers with detailed explanation. If you are satisfied with my explanations please THUMBS UP.. Thanks inadvance for your support dear....

Answer

C. post-hoc comparisions after completing an ANOVA

Reason : ANOVA is testing several means at a time. So we don't get comparison of two means at a time. So after completing ANOVA we have to conduct a Multiple Comparison Test which is done by Post Hoc comparisons. That is why ANOVA is called an omnibus test
