To graph the main effect from a two-way ANOVA, the levels of one factor (independent variable) are plotted along the X axis, the dependent variable is plotted along the Y axis, and the main effect means are plotted in the graph. This is because the main effect represents the overall effect of one independent variable on the dependent variable, while holding the other independent variable constant. Therefore, we need to graph the levels of one factor against the dependent variable while averaging across the levels of the other factor. The main effect means represent these averaged values for each level of the factor being plotted on the X axis.
