WebBecause a main effect is the effect of one independent variable on the dependent variable, ignoring the effects of other independent variables, you will have a total of two potential … In factorial designs, there are three kinds of results that are of interest: main effects, interaction effects, and simple effects. A main effectis the effect of one independent variable on the dependent variable—averaging across the levels of the other independent variable. Thus there is one main effect to consider … See more The results of factorial experiments with two independent variables can be graphed by representing one independent variable on the x-axis and … See more There is an interactioneffect (or just “interaction”) when the effect of one independent variable depends on the level of another. Although this might seem complicated, you … See more When researchers find an interaction it suggests that the main effects may be a bit misleading.
