Marketing A marketing research firm wants to determine the most effective method of advertising: print, radio, or television. They recruit 300 volunteers to participate in the study. The chief researcher believes that level of education plays a role in the effectiveness of advertising, so she segments the volunteers by level of education. Of the 300 volunteers, 120 have a high school education, 120 have a college diploma, and 60 have advanced degrees. The 120 volunteers with a high school diploma are randomly assigned to either the print advertising group, the radio group, or the television group. The same procedure is followed for the college graduate and advanced degree volunteers. Each group is exposed to the advertising. After 1 hour, a recall exam is given and the number of correct answers recorded.
(a) What type of experimental design is this?
(b) What is the response variable in this experiment?
(c) What are the treatments?
(d) What variable serves as the block?
(e) Draw a diagram similar to Figure 7, 8, or 10 to illustrate the design.
