What is literature review? B. List six need for literature review in research methods

A. What is literature review?

A literature review is a comprehensive summary and critical analysis of previous research, scholarly articles, books, and other sources relevant to a particular topic or research question. Its purpose is to provide an overview of current knowledge, theories, and findings, identifying gaps, inconsistencies, and areas needing further investigation.

B. List six need for literature review in research methods

1. Identifies Research Gaps: It helps researchers discover what has already been studied and, more importantly, what areas still need investigation, thus justifying the need for their own study.
2. Avoids Duplication: It prevents researchers from unknowingly repeating studies that have already been conducted, ensuring efficient use of resources and effort.
3. Provides Theoretical Framework: It helps to ground the current research within existing theories and conceptual models, giving the study a solid theoretical foundation.
4. Informs Research Design: By examining previous methodologies, researchers can learn from others' successes and challenges, helping them select appropriate research designs, data collection tools, and analytical approaches for their own study.
5. Contextualizes the Study: It places the current research within the broader body of knowledge, showing how it relates to and builds upon previous work in the field.
6. Identifies Key Variables and Concepts: It helps researchers understand the important variables, concepts, and terminology used in their field, ensuring clarity and precision in their own study.
