In dissertation or thesis work, the empherical literature review is usually the second chapter of both the proposal and the final paper. In this chapter, the author reviews the information and theories currently available concerning the topic and the historical background of the topic. The point is to do two things. First, it is to demonstrate the candidate's thorough understanding of the field in which he/she is conducting research. Second, it is to show that the problem being studied has not be done before or has not been done before in the way proposed by the candidate. The literature review may also contain a review of information concerning the chosen conceptual framework, to show it is appropriate, and the methodology, although most of this information is usually saved for the appropriate sections in chapters 1 and 3 of the paper.

Empirical review in research methodology involves examining evidence from observations or experiments to draw conclusions. It is based on data gathered through systematic methods such as surveys, interviews, or experiments to test hypotheses and answer research questions. This approach ensures that research findings are supported by empirical evidence rather than speculation.
A method refers to a specific procedure or technique used to carry out a task or research. Methodology, on the other hand, encompasses the theoretical framework and overall approach guiding the use of methods to address a research problem or achieve a goal.
Research design refers to the overall plan that outlines how a research study will be conducted, including the approach, procedures, and data collection methods. Methodology, on the other hand, refers to the theoretical framework or process used to conduct research, outlining the specific techniques and tools that will be used to gather and analyze data. In summary, research design is the blueprint of the study, while methodology is the strategy for executing that blueprint.
Medical research often involves a combination of both empirical and theoretical approaches. Empirical research relies on data and observations gathered through experiments or direct measurements, while theoretical research involves the development of conceptual frameworks and models to explain phenomena. Both aspects are important for advancing our understanding of medical conditions and developing new treatments.
To determine if the conclusion of empirical research is logically supported, you should examine the research methodology, statistical analysis, and the coherence between the data collected and the conclusion drawn. Check if the study design, sample size, data collection methods, and statistical tests used are appropriate. Additionally, look for any biases or confounding variables that may have influenced the results.
Typically, the methodology section in a thesis should be around 10-15% of the total length of the thesis. This can vary depending on the specific requirements of your institution and the complexity of your research methods. Aim for clarity and detail in presenting your research methodology.
