The progress of a dissertation directly depends on the methodology chosen by the researcher. It is the methodology that determines whether the experiments or the analysis of the necessary data will be conducted correctly, as well as the value of the results obtained. What types of research methods exist? What should you pay attention to when choosing them? How should they be properly justified? We will explain this in more detail below.
Research methods: what types are there?
Since dissertation research has different aims and objectives, the methodology for conducting it also varies. In general, it can be divided into several types, which we will examine in detail.
| Type of method | Description | Main methods |
|---|---|---|
| Quantitative methods | Focus on numerical data, measurements, and statistical analysis. Used for testing hypotheses, identifying patterns, and determining relationships between variables. |
|
| Qualitative methods | Collection and analysis of non-numerical data. This approach focuses on understanding complex phenomena, human experiences, perspectives, and motivations. |
|
| Mixed methods | A combination of quantitative and qualitative approaches for a comprehensive understanding. For example: surveys + interviews to explain results. |
|
| Theoretical methods | Used for creating, analysing, or generalising knowledge, constructing scientific laws, principles, and patterns without empirical data. |
|
| Conceptual methods | Aimed at interpreting, clarifying, and systematising concepts, as well as constructing theoretical models and structures within a specific field of knowledge. |

How to choose and justify methods in a dissertation
1. Analyse the research problem and the aims of the study
First, analyse the essence of the research problem you are addressing. Then clearly formulate the aims and objectives of the dissertation, as each method must correspond to a specific research task. For example, if the objective is to identify patterns, choose quantitative methods, while for understanding motivations, choose qualitative ones.
2. Analyse the work of other researchers
Familiarise yourself with dissertations and publications by other researchers in your field to understand which methods are used most frequently. Pay attention to how these researchers justified their choice of methods. If you plan to deviate from traditional approaches, prepare a convincing argument explaining why your choice is more appropriate for solving the stated issue.
3. Assess available resources
Realistically evaluate your capabilities: time frame, budget, access to respondents, databases, or technical equipment. Also, take into account your competencies: if the method requires complex statistical analysis, ensure that you possess the necessary skills.
4. Acknowledge the limitations of the chosen methods
Critically assess the weaknesses of your chosen methodology. Honestly describe potential errors or limitations of your results. For example, indicate if your sample is not sufficiently representative. It is important to show that you are aware of these shortcomings and have taken possible measures to minimise them.
5. Demonstrate consistency between the methods and the theoretical framework
Show how the selected methods logically follow from the theoretical foundation of your research. Refer to key works that form your theoretical basis. Such consistency demonstrates the systematic nature of your study and convinces reviewers of the logical coherence of your chosen methodology.
The correct choice and justification of methods in a dissertation ensure its scientific value and increase the chances of a successful defence. Following the steps described above guarantees the logical structure and consistency of the research.
