Refer to Exercise 9.10. In addition to the factor, Type of advertisement (within-store price promotion and between-store price promotion), the researchers also investigated the impact of a second factor-Location where ad is read (at home or in the store). About half of the consumers who were assigned to the within-store price promotion read the ad at home, and the other half read the ad in the store. Similarly, about half of the consumers who were assigned to the between-store price promotion read the ad at home, and the other half read the ad in the store. In this second experiment, the goal was to compare the average discount values of the groups of consumers created by combining Type of advertisement with Location.
