Two-Way ANOVA Test with No Interaction
Let’s take a look at the two-way ANOVA test for factorial models that have no interaction between factors.
We'll cover the following
A two-way ANOVA test with no interaction
As we build up toward a full factorial analysis, we can fit a model with the two factors Light and Fert. The model below doesn’t allow for interaction yet. Since the subset of the data excludes the combined treatment, it isn’t possible to look for interaction anyway. Take a look at the code widget below to see the coefficients of the two-way ANOVA test:
