Factorial Design: Main Effects & Interactions - Study.com

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.

WebFeb 1, 2024 · You can interpret the resolution index as follows: let main effects = 1, two-factor interactions = 2, three-factor interactions = 3, etc. Then subtract this number from the resolution index to show how that effect is aliased. 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.
