What role does a literature review play before conducting research?

A literature review is a critical step in the research process, as it serves to identify and analyze previous research relevant to the study. By reviewing existing literature, researchers can understand the current state of knowledge in their field, recognize gaps or inconsistencies in the research, and refine their research questions or hypotheses. This foundational knowledge ensures that the planned research builds on what is already known and addresses significant issues or questions that require further exploration.

Conducting a literature review allows researchers to position their work within the broader academic conversation and justify their study's relevance. This creates a well-informed base from which to proceed, preventing duplication of effort and promoting the advancement of knowledge.
