5.8.6. Assessing significance of main effects and interactions

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 … 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.

WebFactorial Designs: Main Effects The main effect in a factorial design is "the effect of one independent variable averaged over all levels of another independent variable" ( McBurney, 2004, p. 289). Table 4 below shows hypothetical data for our 2 x 2 factorial design example. WebEach effect in a 2 k model has one degree of freedom. In the simplest case, we have two main effects and one interaction. They each have 1 degree of freedom. So the t statistic is the ratio of the effect over its estimated standard error (standard deviation of the effect).
