What is the role of a literature review in a research study?

The role of a literature review in a research study is to summarize and analyze existing studies relevant to the research question. This involves a comprehensive examination of the existing body of work to identify trends, gaps, and debates within the field. By synthesizing prior research, the literature review helps establish the context for the current study, demonstrating how it contributes to the ongoing academic conversation.

Moreover, it aids in identifying methodological approaches that have been successful or challenged in previous studies, thereby guiding the researcher in framing their own methodology and refining their research questions. This foundation is essential for justifying the need for the new research and can lead to the refinement of hypotheses based on what is already known or debated in the literature. Through this process, the literature review becomes a critical component of a well-structured research project.
