Quizplus · Accepted Answer

Multiple regression analysis with an interaction-effect is the best choice for testing the hypothesis as it allows for the investigation of the relationship between the two variables (quality of tangible elements and satisfaction) and the potential moderating effect of the student/faculty status on this relationship. ANOVA and MANOVA only examine differences between groups and cannot test interaction-effects. Three multiple regression models are not necessary as they are often used for mediation testing, which is not relevant to the hypothesis in question.
