Experiment With multiple explanatory variables What are the effects of repeated exposure to an advertising message? The answer may depend on both the length of the ad and on how often it is repeated. An experiment investigated this question using undergraduate students as subjects. All subjects viewed a 40-min television program that included ads for a digital camera. Some subjects watched a 30 second commercial; others watched a 90-second version. The same commercial was shown either 1, 3, or 5 times during the program. After viewing, all the subjects answered questions about what they recalled of the ad, their attitudes toward the camera, and their intention to purchase. Problem: For the advertising study, a) Identify the explanatory and response variables, and b) List all of the treatments.
