The effects of each individual variable on the outcome.

Independent variable in a factorial design.

Different values or conditions of an independent variable.

Calculated by multiplying the number of levels of each independent variable in the design.

A design with two IVs each having two levels, as demonstrated in the text with cell phone use and time of day example.

An independent variable that is measured but cannot be manipulated by the researcher.

Factorial designs usually have 2-3 independent variables with 2-3 levels each due to increasing number of conditions and participants.

Method of assigning participants to the different combinations of IV levels in a factorial experiment.

A single independent variable's impact on a dependent variable, regardless of other variables.

The combined impact of two or more independent variables on a dependent variable.

One independent variable's effect differs based on the level of the second independent variable.

Two independent variables alter the dependent variable in opposite directions.

An effect of one independent variable at a particular level of another independent variable, showing how the interaction works.

The interplay effect of several independent variables on the dependent variable.

A research design where all factors involve different participants, with each person receiving only one condition of each factor.

Each subject experiences all conditions of all factors.

One factor varies between subjects, while another factor varies within subjects.

A factorial design where no IV is manipulated.

A variable that is controlled or manipulated to observe its effect on another variable.

The variable measured to see how it is affected by changes of another variable.
