Suppose you have developed a print advertisement for a new brand of fashion clothes and want to determine how much awareness it generates. You have made arrangements with a magazine publisher who has given you telephone numbers of a random sample of its subscribers. You can send some of these people a copy of the magazine with the new advertisement in it and send others copies which are same in every other way but without the advertisement. Awareness will be measured using telephone interviews. In the present case, which of the following two designs will give you a more accurate result: (1) before-after with control group design, or (2) after-only with control group design
