Analytical Problems of Meta-analysis - the Effect of Heterogeneous Studies
Keywords:
meta-analysis, survey effect, combined tests, fail-safe NAbstract
The growing number of issues in social science research has led to a correspondingly large body of research studies. The sheer volume of research related to the same topics poses a question as to how to organise and summarise these findings to identify and use what is known and focus research on promising areas. Effect size estimates from the studies are not identical. This is to be expected because the estimates are based on data from samples, and random variations due to sampling should introduce fluctuations into estimates. This paper introduces methods for exploring these fluctuations as a paradigm for explorations in meta-analyses generally.
