Factorial design is a type of research methodology that allows for the investigation of the main and interaction effects between two or more independent variables and on one or more outcome variable (s).
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.
21 Μαρ 2024 · This article explains factorial designs and two-way ANOVA with the help of a worked example using hypothetical data in a spreadsheet provided as a supplementary file. The main effects and interaction effects are explained and illustrated using tables and figures.
By far the most common approach to including multiple independent variables (which are often called factors) in an experiment is the factorial design. In a factorial design, each level of one independent variable is combined with each level of the others to produce all possible combinations.
In this chapter, we look closely at how and why researchers use factorial designs, which are experiments that include more than one independent variable. Schnall, S., Benton, J., & Harvey, S. (2008). With a clean conscience: Cleanliness reduces the severity of moral judgments.
