Question

Quizplus · Accepted Answer

A factorial design is appropriate for Dr. Fleet's study as she is interested in the effects of multiple independent variables (gender, years of undergraduate college, and marital status) on a dependent variable (annual income). The first factor, gender, has two levels (male/female), the second factor, years of undergraduate college, has five levels (0-4 years), and the third factor, marital status, has four levels (single, married, divorced, widowed). Therefore, a 2x5x4 factorial design would be the most appropriate choice, as it can accommodate all three factors with their respective levels.
