You are comparing spatial ability scores for four groups. you find that the f statistic for your test is 4.01, and the cutoff value you identified prior to your analysis was 3.45. do you reject or fail to reject the null hypothesis and what, if any, other steps do you need to take?
Reject the null hypothesis since your F statistic is beyond the cutoff, and perform a post-hoc test to determine between which groups the significant difference occurs.
