A researcher would conduct a literature review if they want to find out what other studies have unearthed about the research problem of interest.
The process of consulting prior studies on a subject is known as a literature review. This is important because if you conduct a literature review, you might find that your proposed project has already been done. This is why a literature review is a component of the research process that must be conducted first.
The literature review should list, outline, synthesize, critically assess, and clearly state prior research as well as provide a theoretical framework for future research and assist a new researcher in classifying their area of interest.
