Research Limitations
Research limitations refer to the weaknesses or constraints that may affect the validity, reliability, or generalisability of a study. They are an expected part of any research and should be clearly acknowledged and explained in the dissertation.

What is Research Limitations?
It is for sure that your research will have some limitations and it is normal. However, it is critically important for you to be striving to minimize the range of scope of limitations throughout the research process. Also, you need to provide the acknowledgement of your research limitations in conclusions chapter honestly.
It is always better to identify and acknowledge shortcomings of your work, rather than to leave them pointed out to your by your dissertation assessor. While discussing your research limitations, don’t just provide the list and description of shortcomings of your work. It is also important for you to explain how these limitations have impacted your research findings.
Your research may have multiple limitations, but you need to discuss only those limitations that directly relate to your research problems. For example, if conducting a meta-analysis of the secondary data has not been stated as your research objective, no need to mention it as your research limitation.
Research Limitation Points
Research limitations in a typical dissertation may relate to the following points:
1. Formulation of research aims and objectives. You might have formulated research aims and objectives too broadly. You can specify in which ways the formulation of research aims and objectives could be narrowed so that the level of focus of the study could be increased.
2. Implementation of data collection method. Because you do not have an extensive experience in primary data collection (otherwise you would not be reading this book), there is a great chance that the nature of implementation of data collection method is flawed.
3. Sample size. Sample size depends on the nature of the research problem. If sample size is too small, statistical tests would not be able to identify significant relationships within data set. You can state that basing your study in larger sample size could have generated more accurate results. The importance of sample size is greater in quantitative studies compared to qualitative studies.
4. Lack of previous studies in the research area. Literature review is an important part of any research, because it helps to identify the scope of works that have been done so far in research area. Literature review findings are used as the foundation for the researcher to be built upon to achieve her research objectives.
However, there may be little, if any, prior research on your topic if you have focused on the most contemporary and evolving research problem or too narrow research problem. For example, if you have chosen to explore the role of Bitcoins as the future currency, you may not be able to find tons of scholarly paper addressing the research problem, because Bitcoins are only a relatively recent phenomenon.
5. Scope of discussions. You can include this point as a limitation of your research regardless of the choice of the research area. Because (most likely) you don’t have many years of experience of conducing researches and producing academic papers of such a large size individually, the scope and depth of discussions in your paper is compromised in many levels compared to the works of experienced scholars.
How to Address Research Limitations
You can discuss certain points from your research limitations as the suggestion for further research at conclusions chapter of your dissertation.
Research limitations should be addressed primarily in the conclusion chapter, but they should also be considered throughout the research process. Acknowledging limitations strengthens the credibility of your research rather than weakening it.
You should:
- Acknowledge limitations honestly and clearly
- Focus only on limitations that directly affect your research findings
- Explain how each limitation impacts results and conclusions
- Suggest how future research could overcome these limitations
