Which of the following is the general format for describing factorial designs?

A) Number of levels of first IV × Number of levels of second IV
B) Number of IVs × Total number of levels
C) Number of main effects × Number of interactions
D) Number of conditions of first IV × Number of conditions of second IV

Factorial Designs

Experimental strategy that involves testing more than one independent variable at the same time, to study their effects and interactions.

Independent Variable (IV)

A variable in an experiment that is manipulated by the researcher to observe its effect on the dependent variable.

Levels

Refers to the different values or states that an independent variable can take on in an experiment or study.
