Between Subjects Factorial Design

Flashcards about factorial designs in experiments, covering main effects, interactions, and design layouts.

Factorial Designs

Designs in which we study two or more independent variables at the same time.

Factors

Independent Variable; each factor will have two or more levels.

Main Effects

The action of a single independent variable in an experiment; a change in behavior associated with a change in the value of a single independent variable or factor in the experiment.

Interactions

An interaction is present if the effect of one independent variable changes across the levels of another independent variable.

Laying out the Factorial Design

Indicate the two independent variables, the levels of Factor 1, the levels of Factor 2, and the four treatment conditions.

Factor-Labeling Method

A method of describing design variables, such as '2 x2 (Type of Name x Length of Name) between-subjects factorial design'.

Factor and Levels Method

A method of describing design variables, such as '2 × 2 (Type of Name: given, nickname × Length of Name: short, long) between-subjects factorial design'.
