meta-analysis

Statistics

A statistical methodology in which data from previous tests are considered and analysed together. For example, a series of small experiments may all show only slight signs of the same effect (e.g. that one medicine is better than another), whereas the aggregation of the experiments provides overwhelming evidence. A difficulty with this approach is that experimental conditions and experimental protocols may vary, so that the aggregate outcome may not be a fair reflection of the true situation.

Economics

Combining the results of several studies that address the same research hypotheses to produce an overall conclusion, typically in the form of a quantitative literature review or a summary. For example, the simplest meta-analysis would be to average the results of previous research. A range of statistical techniques have been designed to undertake meta-analysis.
