What is the scientific benefit of writing a review of sources in Master's and Doctoral thesis? Is it just to see the work of other researchers or to cite and enhance your research work?
In a thesis, a comprehensive review of works done on the subject selected for the study and the lacunae in the subjects are presented as a chapter. After going through the review, one should get answer to the question: “What was the level of knowledge on the chosen topic just before the experiment?”
Present the findings of various authors interconnecting them with your observations. In a thesis, the review is meant to present not only up-to-date knowledge of the field but also the intellectual ability of the student to synthesize and put together information from different sources. Proper guidance from the research guide is necessary to have a good review of literature.
In a review, include only those works, which are relevant to the problem investigated. For some topics, you may find numerous references, and it is impossible to review all of them. You then chose the most relevant and the latest ones. On the contrary, for certain topics, there may not be many references directly relevant to the study. In such cases, you have to search sources of information on related topics. Remember that it is not the number of references that matters but their relevance.
The depth of scientific review shows the degree of involvement of the applicant in the problem. It also shows what was done before the author. This part is present in any scientific work: an article, theses, monographs, etc.
The review is important because: It enhances our research study. It describes how the proposed research is related to prior research in statistics. It also shows the originality and relevance of the research problem.
Interesting question. It’s very important to do in depth search regarding MSc or PhD thesis to be aware about the relevant problem (s) inside out and if the anyone else have tackled it and in which aspects
