Question

What is significant of anova?

Answer 1

In its simplest form, ANOVA provides a statistical test of whether or not the means of several groups are equal, and therefore generalizes the t-test to more than two groups. ANOVA is useful for comparing (testing) three or more means (groups or variables) for statistical significance. It is conceptually similar to multiple two-sample t-tests , but is more conservative (results in less type I error )[1] and is therefore suited to a wide range of practical problems.
