What utility does a literature review provide in research?

A literature review plays a crucial role in situating research within the existing body of knowledge. By examining previous studies, theories, and findings, it allows researchers to identify gaps in the literature, understand the context of their work, and demonstrate how their research contributes to or challenges existing understandings in the field. This process not only establishes the relevance and importance of the new research but also provides a foundation for formulating research questions and methodologies.

The option that mentions summarizing only recent studies misrepresents the purpose of a literature review, which encompasses a broad range of both recent and relevant historical studies. Focusing solely on quantitative data limits the breadth of research insights, while the notion that it restricts the scope of the study overlooks the literature review's role in broadening perspectives by incorporating diverse findings and viewpoints. Thus, a literature review is essential for grounding new research in a well-established framework, fostering an informed approach to inquiry.
