Which is the purpose of conducting a literature review for a research study?
Describe how the study findings can be used in the future and identify the need for conducting the study.
Provide a context for the research question that describes relevant theory and results of previous studies.
Ensure that the study has not already been completed and that the findings will provide a unique contribution.
Identify the research design and explain the rationale for choosing the research methodology.
The Correct Answer is B
A. While a literature review may discuss the potential implications of the study findings for future research or practice, its primary purpose is to provide background information and theoretical framework for the research question.
B. Providing a context for the research question involves describing relevant theories, concepts, and findings from previous studies that inform the current study. This helps justify the research question, refine hypotheses or research objectives, and guide methodology and interpretation of results.
C. Ensuring that the study has not already been completed is one aspect of a literature review, but its broader purpose is to review existing literature to build on previous knowledge and identify gaps in the literature that the current study can address.
D. While the literature review may provide insights into different research designs used in previous studies, its primary purpose is not to identify the research design or explain the rationale for choosing the research methodology.
