What Does A One Way Anova Tell You. If your one-way ANOVA p-value is less than your significance level you know that some of the group means are different but not which pairs of groups. This tutorial explains the following.
Use the grouping information table and tests for differences of means to determine whether the mean difference between specific pairs of groups are statistically significant and to estimate by how much they are different. If your test returns a significant f-statistic you may need to run an ad hoc test like the Least Significant Difference test to tell you exactly which groups had a difference in means. Specifically it tests the null hypothesis.
Below I have mentioned the steps to perform one-way ANOVA in Excel along with a post-hoc test.

When you use ANOVA to test the equality of at least three group means statistically significant results indicate that not all of the group means are equal. Why is that useful.
