The Advantages of Meta-Analysis. Meta-analysis is an excellent way of simplifying the complexity of research. A single research team can reasonably only output so much data in a given time. But meta-analysis gives access to possibly more data than that team could produce in a lifetime, and allows them to condense it in useful ways.
