The literature review is important to undertake because it describes how the proposed research is related to prior research in statistics. It discusses published information in a particular subject area. It shows the originality and relevance of my research problem. It justifies my proposed methodology. It demonstrates my preparedness to complete the research.
By the literature search and review on my research question, I will discover what related statistical knowledge exists. Increase my knowledge in my research area. Avoid duplicating results of other statisticians. Justify the relevance of my proposed research.
A literature review can be just a simple summary of the sources, but it usually has an organizational pattern and combines both summary and synthesis. A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information. It might give a new interpretation of old material or combine new with old interpretations. Or it might trace the intellectual progression of the field, including major debates. And depending on the situation, the literature review may evaluate the sources and advise the reader on the most pertinent or relevant University of North Carolina at Chapel Hill (n.d.).
