Quizplus · Accepted Answer

Meta-analysis is the statistical technique used to combine the results of multiple studies in order to provide a broad perspective on a particular area of research. It involves a systematic review of relevant literature, identification of relevant studies, evaluation of their quality, and synthesis of the results using statistical methods. Standard deviation, correlation, and means analysis are useful in evaluating individual studies or analyzing data from a single study, but they do not provide the same level of overview that is possible through meta-analysis.
