Quizplus · Accepted Answer

A within-subjects design involves participants being exposed to all levels of the independent variable, in this case, all three different pale ales were rated by Wally. This is in contrast to a between-subjects design where participants are only exposed to one level of the independent variable. A factorial design involves manipulating two or more independent variables, which is not the case here, and an independent groups design is another term for a between-subjects design. Therefore, the best choice is D, within-subjects.
