In a two-way ANOVA, three F scores are calculated. This statistical method is used to examine the interaction between two independent variables and their influence on a dependent variable.

The F scores include:

  1. The main effect of the first independent variable, which tests whether the levels of this variable significantly affect the dependent variable.
  2. The main effect of the second independent variable, which evaluates whether this variable has a significant effect on the dependent variable, independent of the levels of the first variable.
  3. The interaction effect, which assesses whether the combination of the two independent variables affects the dependent variable in a way that is different from their individual effects.

This three-way calculation helps in understanding not only the separate impacts of each factor but also how they interact with one another.
