Quizplus · Accepted Answer

Lawrence should use a between-groups design, also known as an independent groups design. Each audience should only see one commercial to ensure that the ratings are not influenced by previous exposure to other advertisements. A between-groups design involves assigning different groups of participants to each condition, in this case, each commercial. This will allow Lawrence to compare the ratings between the different commercials to determine which commercial receives the highest rating.
