Quizplus · Accepted Answer

The design is best described as a 2 × 2 factorial design because there are two independent variables being manipulated: amount of time studying Chinese (1 or 2 hours per week) and grade level (eleventh or twelfth). Each independent variable has two levels, resulting in a 2 × 2 design.
