Advanced Experimental Designs

These flashcards cover essential vocabulary related to advanced experimental designs, particularly factorial designs, independent variables, and single-subject designs.

Factorial Design

A research design that examines the influence of two or more independent variables (IVs) on a dependent variable (DV).

Independent Variable (IV)

The variable that is manipulated in research to observe its effect on the dependent variable.

Main Effect

The overall effect of an independent variable on the dependent variable, measured without interaction with other variables.

Interaction

A situation in factorial designs where the influence of one independent variable on the dependent variable changes depending on the level of another independent variable.

Mixed-Factorial Design

A research design that includes at least one between-subjects variable and at least one within-subjects variable.

Between-Subjects Design

An experimental design in which each participant is assigned to a single condition.

Within-Subjects Design

An experimental design where each participant is involved in all conditions of the experiment.

Quasi-Independent Variable

A variable that is not truly independent due to lack of manipulation by the researcher but can be treated as a factor in mixed-factorial designs.

Baseline Phase

A series of observations of the same individual without any treatment being administered, used to compare against treatment effects.

Treatment Phase

A series of observations of the same individual after a treatment is administered, aimed at evaluating treatment effects.
