Research synthesis is the process of systematically collecting and analyzing existing research studies on a particular topic in order to develop a comprehensive understanding and consensus on the current state of knowledge in that area. It involves reviewing, summarizing, and synthesizing the findings of multiple studies to draw meaningful conclusions, identify gaps in the research, and make recommendations for future studies or policy implications. Research synthesis may include various methods such as meta-analysis, systematic reviews, scoping reviews, and literature reviews. The goal of research synthesis is to provide an evidence-based understanding of a particular topic by considering a wide range of studies and perspectives.
