Quizplus · Accepted Answer

The overall F-test in the analysis of variance is called an omnibus test because it tests the null hypothesis that all group means are equal. It is a statistical test used to determine whether there are differences between at least two groups in terms of their means on a particular variable. It is not related to effect size, post-hoc tests, or zero order tests.
