Meta-analysis is a method of synthesis of quantitative data from multiple independent studies addressing a common research question. An important part of this method involves computing a combined effect size across all of the studies.
The smallest unit of analysis in the social sciences is an individual in their social setting. At the micro level, also referred to as the local level, the research population typically is an individual in their social setting or a small group of individuals in a particular social context.
A metatheory or meta-theory is a theory on a subject matter that is a theory in itself. [1] Analyses or descriptions of an existing theory would be considered meta-theories. [2] If the subject matter of a theoretical statement consists of one or multiple theories, it would also be called a meta-theory. [3]

A meta-analysis is a statistical analysis that combines the results of multiple quantitative studies. Using statistical methods, results are combined to provide evidence from multiple studies. The two types of data generally used for meta-analysis in health research are individual participant data and aggregate data (such as odds ratios or ...
Meta-analysis is a method used to combine the results of different trials in order to obtain a quantitative synthesis. The size of individual clinical trials is often too small to detect treatment effects reliably. Meta-analysis increases the power of statistical analyses by pooling the results of all available trials.
Meta-analyses have their own methodological problems and disputes, which leads to rejection of the meta-analytic method by researchers whose theory is challenged by meta-analysis. [117] Rosenthal proposed the "fail-safe number" (FSN) [54] to avoid the publication bias against null results. It is defined as follows: Suppose the null hypothesis ...
