The design is a factorial design with four independent variables: lecture type (4 levels), classroom size (2 levels), presentation method (3 levels), and instructor (3 levels). Each variable has multiple levels, making this a 4 × 2 × 3 × 3 design. The study also appears to use different groups of participants for each combination of independent variables, making it a between-groups design. Therefore, the best choice is a 4 × 2 × 3 × 3 between-groups ANOVA (D).
