WebExplain why researchers often include multiple independent variables in their studies. Define factorial design, and use a factorial design table to represent and interpret simple factorial designs. Distinguish between main effects and interactions, and recognize and give examples of each. WebMar 12, 2024 · In factorial designs, multiple independent variables are tested simultaneously. Each level of one independent variable is combined with each level of every other independent variable to create different conditions. In a mixed factorial design, one variable is altered between subjects and another is altered within subjects.
