Results could be any of the following: Drug X could have a main effect, where Drug Y has no effect. An interaction is a result in which the effects of one experimental manipulation depends upon the experimental manipulation of another independent variable. In a factorial research design, the main effect is an important feature to consider. Its clear that inpatient treatment works best, day treatment is next best, and outpatient treatment is worst of the three. A 22 factorial design is a type of experimental design that allows researchers to understand the effects of two independent variables (each with two levels) on a single dependent variable. As far as I can tell, the DV's data might not suit the requirements for normal distribution for an ANOVA since data is bounded 0 and 100, respectively.
