Document Summary

Introduction: factorial design includes two or more independent variables and crosses (i. e. , combines) every level of each independent variable with every level of all the other independent variables. Basic characteristics of factorial designs: most basic factorial design possible is combining two independent variables, which have two levels each, creating an experimental design that has four conditions. Examining interactions between independent variables: studying both variables in the same experiment allows us to determine whether the way one independent variable influences behaviour differs, depending on the level of a second independent variable. Designing a factorial experiment: practical limitations often necessitate a choice between adding independent variables to a factorial design or adding more levels to a smaller number of independent variable. The person x situation factorial design: person x situation (also called person x environment) factorial design an experiment design that incorporates at least one subject variable along with at least one manipulated situational variable.
