In Metasyntheses, Various Methods Are Employed for Interpretive Analysis

In metasyntheses, various methods are employed for interpretive analysis. One method developed by Paterson and a team of Canadian colleagues (2001) involves three components: meta-data analysis, meta-method, and meta-theory. A meta-data analysis involves which of the following?

A) The study of the results of reported research in a specific substantive area by analyzing the "processed data"
B) The study of the methodologic rigor of the studies included in the meta-synthesis
C) The analysis of the theoretical underpinnings on which the studies are grounded
D) The splitting of effect size information into distinct categorical groups
