What are two common reasons to use a factorial design? Describe why Bartholow and Heinz's word association study on alcohol and thoughts of aggression was a factorial design
Homework Answers
- Factorial designs can test limits; to test whether an independent variable effects different kinds of people, or people in different situations, the same way.
- Factorial designs can test theories; can test generalizability of a causal variable and also test theories.
- Researchers can use factorial designs not only to test the generalizability of a causal variable but also to test theories.It was a factorial design because it consisted of 2 independent variables, photo type and word type.The resulting interaction supported one reason that alcohol causes aggressive behavior. People cognitively associate alcohol cues with aggressive concepts.

Lesson: -Factorial designs have more than one independent variable or factors. -A two way factorial design has two independent variables, a three-way factorial design has three independent variables and so forth. -A 2x2 design has two factors and two levels of each. -A 2x3 design also has two factors but one has two levels and one has three. -A 3x3 design has two factors and each factor has 3 levels. Each example has 2 independent variables or factors. Comparison of...
