Q5 An advertising agency has been hired by a manufacturer of pens to develop an advertising campaign for the upcoming holiday season. To prepare for this project, the research director decides to initiate a study of the effect of advertising on product perception. An experiment is designed to compare five different advertisements. Advertisement A: greatly undersells the pen's characteristics. Advertisement B: slightly undersells the pen's characteristies. Advertisement D: greatly oversells the pen's characteristics. Advertisement E: attempts to correctly stat the pen's characteristics. A sample of 25 adults respondents, taken from a larger focus group, is randomly assigned to the five advertisements (so that there are five respondents to each). After reading the advertisement and developing a sense of "product expectation," all respondents unknowingly receive the same pen to evaluate. The respondents are permitted to test the pen and the plausibility of the advertising copy. The respondents are then asked to rate the pen from 1 to 7 (lowest to highest) on the product characteristic scales of appearance, durability, and writing performance. Table Q5 shows the combined scores of three ratings (appearance, durability, and writing performance) for the 25 respondents. Table Q5: Combined scores of three ratings Advertisement A D E 15 16 8. 12 18 17 7 6. 19 17 21 10 13 18 19 16 15 11 12 10 10 14 17

A researcher wants to test a new memory performance supplement that has shown some promise in primate studies where subjects were given the supplement followed by the task of identifying pictures of other animals three days later. The dependent variable was measured by the number of pictures correctly identified. The researchers noticed that while there was a positive correlation between the group given the supplement and number of correctly identified pictures as compared to the control group, they also notice that there seemed to be some variation between the males and females of the primates. Additionally, two different amounts of the drug have been proposed for consideration. Therefore, in the current study, the researchers want to divide the subject primates (N=60) by gender (male: n=30; female: n=30), and give them a 10 mg dose in one treatment condition, and a 25 mg dose in the other treatment condition. To do this, they are dividing each group of males and females in half, and…
