Meta-analysis is the term that best describes a systematic approach to combining data from multiple studies. This method involves a statistical synthesis of results from different research works to arrive at a more comprehensive understanding of a particular research question or hypothesis. By aggregating findings, meta-analysis can enhance the overall power of the study, identify patterns and discrepancies among studies, and provide a clearer picture of the evidence available on a topic.

This process often includes setting strict criteria for including studies, thus ensuring that the studies being combined are relevant and of sufficient quality. This critical assessment helps in minimizing bias and leads to more reliable conclusions.

In contrast, qualitative analysis focuses on examining non-numerical data to understand concepts, thoughts, or experiences, and does not involve combining data in a quantitative manner. A case study is an in-depth exploration of a single instance or context, and survey research gathers information from individuals through questionnaires or interviews but does not inherently involve synthesizing data from multiple studies.
