Exercise 1. Vote Counting Scenario When Polly was in graduate school, she began to work on a meta-analysis examining the influence of peermentoring programs on academic achievement for high school students. She searched all published issues of the major journals in education and was disappointed to find that 12 of the 20 studies that she retrieved reported that participation in peer-mentoring programs did not result in increased achievement. As a result, she abandoned the project.

Do you think that Polly made a wise decision? What, if any, mistakes did she make during her attempt to synthesize the relevant literature? What would you recommend that she do to improve her techniques?
