In a factorial design a main effect is the
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 representing the other by using different colored bars or lines. (The y-axis is always … 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 already have an intuitive understanding of … See more When researchers find an interaction it suggests that the main effects may be a bit misleading. Think of the example of a crossover interaction … See more WebIt is called a factorial design, because the levels of each independent variable are fully crossed. This means that first each level of one IV, the levels of the other IV are also manipulated. “HOLD ON STOP PLEASE!” Yes, it seems as if we are starting to talk in the foreign language of statistics and research designs. We apologize for that.
