University of Central Florida (UCF) PSY3204C Statistical Methods in Psychology Practice Quiz 3

In a 3 x 5 x 9 design, each number represents the number of levels for each independent variable in the study. The notation indicates that there are three independent variables, and the counts associated with each are the levels of those variables.

In this case, the first independent variable has 3 levels, the second independent variable has 5 levels, and the third independent variable has 9 levels. Therefore, identifying the levels of the second independent variable directly leads us to conclude that it has 5 levels. Understanding how to read the notation of factorial designs is crucial, as it helps clarify how many levels are associated with each factor involved in the experiment.
