What is a key purpose of conducting a literature review in research?

Conducting a literature review serves several critical purposes in the research process, one of which is to identify gaps in current studies. This aspect is essential because it allows researchers to understand what has already been explored and where there may be unanswered questions or areas that require further investigation. By recognizing these gaps, researchers can formulate research questions that are both relevant and necessary, thereby contributing new knowledge to their field.

This process also ensures that the research builds on existing work and does not unnecessarily duplicate efforts, making it a foundational step in the development of a robust research project. Identifying gaps helps in shaping the direction of future research, guiding the researcher towards making significant contributions that advance understanding in their area of study.
