Reject the null hypothesis since her F statistic is beyond the cutoff, and perform a post hoc test to determine between which groups the significant difference occurs.
Given,
In the question:
Gretchen is comparing verbal ability scores for four groups. she finds that the f statistic for her test is 4.01, and the cutoff value she identified prior to her analysis was 3.45.
