Offered Previously as PSYC 420

Instructor Consent Required

Description: This course provides background on the methodology of research synthesis, including the literature review and the place of quantitative methods in drawing conclusions from existing research. The course introduces the statistical techniques of meta-analysis, which aggregates and integrates the results of independent studies addressing the same hypothesis. Problem sets provide instruction in making meta-analytic decisions as well as using computer programs to perform meta-analysis. It is valuable for students to have completed one year of graduate statistics and to be familiar with the statistical methods commonly used to analyze behavioral data. Each student enrolled in the course conducts an original small-scale meta-analysis of his or her own, which allows him or her to focus on a project of special self-interest. We begin the course by reading and discussing in class Hunt’s (1997) How Science Takes Stock: The Story of Meta-Analysis. Subsequently, the main readings are assigned from Lipsey and Wilson’s (2001) Practical Meta-Analysis, supplemented by other papers on meta-analysis. Each week features a “meta-analysis of the week” on which discussion centers.

Topics in this course may include: Introduction to meta-analysis; Formulating a research problem; Searching the literature; Evaluating the literature; coding studies; Computing effect sizes (2+ weeks); Analysis of meta-analytic databases (3+ weeks); Interpreting meta-analytic results (2 weeks); Reporting the results of research synthesis; Putting it all together; Lingering issues.
