Taking off from the previous chapter, and following the same workflow, we show you how to make R perform two slightly more complex statistical tests, including the two-way ANOVA and analysis of covariance (ANCOVA). We provide in-depth insight into interpreting coefficients and interaction terms, making predictions from the models, and producing figures. We reiterate how to clearly communicate the outcome of these more complex statistical tests.

Keywords:   statistics, two-way ANOVA, interaction, ANCOVA, prediction, communicate
