9. Factorial Designs

A set of flashcards to help review key concepts related to factorial designs in research methods, emphasizing definitions and explanations of critical terminology.

Factorial Designs

Experiments that include multiple independent variables, allowing researchers to study interactions between variables.

2 × 2 design

The simplest factorial design combining two variables, each with two levels.

Between-Subjects Factorial Design

A design where each participant experiences only one condition.

Within-Subjects Factorial Design

A design where each participant experiences all conditions.

Manipulated Variables

Independent variables that are controlled by the researcher.

Non-Manipulated Variables

Independent variables that are measured but not controlled.

Main Effects

The impact of one independent variable on the dependent variable, averaged across other variables.

Interaction Effects

Occur when the effect of one variable depends on another.

Spreading Interactions

One variable affects the dependent variable at one level but not at another.

Cross-Over Interactions

Effects of one variable are opposite at different levels of another variable.

Simple Effects

Examining the effects of one independent variable at each level of another.

Graphical Representations

Visual tools like bar graphs and line graphs that help convey complex data in factorial experiments.
