This experiment represents a factorial design with three independent variables (age, gender, and job type), each with multiple levels. The levels for age are young, middle, and old. The levels for gender are male and female. The levels for job type are blue collar and white collar. The design is 3 x 2 x 2 because there are three independent variables, with 2 levels for each of the last two variables, resulting in 12 experimental conditions.
