A literature review matrix is a tool used by researchers to analyze and synthesize information from various sources relevant to their research topic. It typically takes the form of a table or chart, where rows represent different studies or articles, and columns display key information such as research methodologies, findings, and key themes.
The primary purpose of a literature review matrix is to help you analyze and compare existing literature, to identify patterns, gaps, and contradictions in the body of knowledge related to your research question.
