Abstract: | The purpose of this article is to provide higher education researchers with an illustrative example of meta-analysis utilizing
hierarchical linear modeling (HLM). This article demonstrates the step-by-step process of meta-analysis using a recently-published
study examining the effects of curricular and co-curricular diversity activities on racial bias in college students as an
example (Denson, Rev Educ Res 79:805–838, 2009). The authors present an overview of the meta-analytic approach and describe a meta-analysis from beginning to end. The example
includes: problem specification; research questions; study retrieval and selection; coding procedure; calculating effect sizes;
visual displays and summary statistics; conducting HLM analyses; and sensitivity analyses. The authors also offer guidelines
and recommendations for improving the conduct and reporting of research which in turn can provide the information necessary
for future and more comprehensive meta-analytic reviews. |
