How to prepare research methodology for a diploma thesis?
The methodological chapter is the manual for your study. After reading it, the reader should know what exactly was checked, how the data was collected and why the chosen method fits the problem. Generic formulas are not enough - the methodology must correspond to what has actually been done.
Key information
- ✓The method is selected to suit the research problem, not the other way around.
- ✓The goal, questions, hypotheses and method of analysis must form one logical system.
- ✓The description of the trial should explain not only who participated, but also how participants were selected.
- ✓The chapter describes the research performed, so avoid declarations that you do not implement later.
Purpose of research
The purpose of the research should clearly indicate what the author wants to check, describe or explain. It shouldn't be too general.
A good research goal is related to the topic of the work and leads to research questions and the selection of an appropriate method.
Problem and research questions
The research problem is the main question that the work aims to answer. Detailed questions develop this problem and structure the analysis.
It's a good idea to avoid questions that can be answered in one word. Questions that allow for analysis, comparison or interpretation of results are better.
Research methods and tools
The research method describes how the research is conducted, e.g. survey, interview, document analysis or case study.
A research tool is a specific instrument, e.g. a survey questionnaire, an interview script or an analysis sheet.
Description of the research sample
The methodology should describe who participated in the study, how many people were included in the analysis and why such a group was selected.
If the research concerns a company, school, institution or professional group, it is worth briefly justifying the choice of respondents.
Quantitative or qualitative research?
Quantitative research helps measure the frequency of phenomena, compare groups and analyze relationships. Qualitative research allows for a deeper understanding of experiences, motivations and how events are interpreted. The choice should be based on the research question, not on the belief that a survey is always easier.
It is also possible to combine both approaches. For example, a survey can show the scale of the problem, and interviews can explain its causes. However, such a project requires time and a clear description of how both types of data will be combined.
How to describe the course of the study and data analysis?
The reader should know when and where the study was conducted, how participants were reached, whether participation was voluntary and how long the material collection took. It is also worth indicating the criteria for including and excluding data from the analysis.
The description of the analysis must correspond to the type of material. For a survey, these will include, for example, descriptive statistics and relationship tests, and for interviews - coding statements and isolating categories. The mere information that the results were "analyzed" is too general.
Ethics, anonymity and limitations of research
The chapter should explain how to inform participants, protect data and ensure anonymity, if applicable to the project. Additional consents may be needed for research carried out in a company, school or medical facility.
Restrictions do not disqualify work. They show that the author understands the limits of inference. A small sample, convenience sampling, short survey time or the declarative nature of the responses should be named and taken into account during interpretation.
Summary
A methodology is convincing when all its elements form one logical sequence: the goal leads to the research questions, the questions determine the method, and the method determines how data is collected and analyzed. There is no need to complicate the description with scientific vocabulary. It is much more important to show precisely what was done, why this solution was chosen and what limitations should be taken into account when interpreting the results.
Frequently asked questions
Does every work have to contain hypotheses?
NO. Hypotheses are typical of studies in which relationships that can be tested are predicted. In qualitative research, well-formulated research questions are often enough.
What is the difference between a method and a research tool?
A method describes how a study is conducted, such as a survey or interview. A tool is a specific instrument, for example a survey questionnaire or an interview script.
When should I write the methodological chapter?
A description of the planned study can be prepared before data collection, but after implementation it must be updated to reflect the actual conduct of the study.
Need support with your work?
Describe the topic, scope and deadline. We will review the materials, recommend the right support and prepare a clear quote.
