An F involving a comparison among the means of the cells is referred to as a test for the significance of the interaction effect in a two-way ANOVA. The interaction effect is the effect of one independent variable on the dependent variable that varies according to the level of the second independent variable. The F-test determines whether this effect is significant or not. The main effect and level effect are tested separately, while a factorial design refers to the combination of factors being considered in the ANOVA.
