Below is an ANOVA summary table. Based on these data, would you follow this ANOVA up with post hoc tests?
| Source | SS | df | MS | F |
| Between-Groups | 60.72 | 3 | 20.24 | 3.88 |
| Within-Groups | 213.61 | 41 | 5.21 | |
| Total | 274.33 | 44 |
Homework Answers
for 0.05 level and (3,41) degree of freedom , critical value of F =2.83
since test statistic 3.88 > critical value 2.83 , we reject null hypothesis at 55 level and conclude that some population means differs
therefore post hoc tests is required to know which means differs,
