A two - way ANOVA test analyzes the effect of the independent variables on the expected outcome along with their relationship to the outcome. This article will explore this important. The two-way analysis of variance is an extension to the one-way analysis of variance.

The additive model assumes that the effects on the outcome. The difference is that where one-way ANOVA only generates one F-value, two - way ANOVA generates three F-values: one to test the main effects of each factor.
