Question

Quizplus · Accepted Answer

The correct method for analyzing this data is two-factor ANOVA because there are two independent variables (factors) involved: the critics and the restaurants, and the response variable is the score given by the critics. This allows for the assessment of the main effects of each factor as well as any interaction effect between the two factors on the scores.
