A political consultant convened a focus group to evaluate the effectiveness of a commercial promoting a candidate. Prior to running any media, the participants are asked to answer one question: Do you intend to vote for Jones in the upcoming election? The participants will respond using a scale ranging from 1 to 7 (1 = Absolutely will not vote for Jones . . . 7 = Absolutely will vote for Jones). Next, the facilitator runs a 30-second radio advertisement, promoting the candidate, after which, the participants are asked to respond to the same question using the 1 to 7 scale.
