A political consulting firm wants to determine the characteristics of voters when it comes to issues involving alternative energy. The researchers recruit a group of participants and randomly assign them to one of three groups: Group 1 will be the control group, and they will not be exposed to any advertising materials; Group 2 will be shown a print advertisement that will be used in a postal mailing; and Group 3 will be shown a video advertisement that will be aired on television. Finally, each participant will indicate his or her voting intentions for Proposition 86, which involves tax deductions for hybrid cars on a 1 to 7 scale (1 = Will definitely vote no . . . 7 = will definitely vote yes).
