Quizplus · Accepted Answer

A factorial design is expressed in terms of two or more independent variables, with each independent variable consisting of multiple levels or conditions. In this study, the independent variables are the grade level (fourth and ninth) and the number of hours of French studied weekly (1, 2, and 3). The order in which these variables are listed is important, so the design is best described as a 3 × 2 factorial design.
