Limitations of a Study Made Easy With This Guide
If you are working on a thesis, dissertation, or other formal research project, chances are your advisor or committee will ask you to address the delimitations of your study.
In a previous articlewe covered what goes into the limitations, delimitations, and assumptions sections of your thesis or dissertation. Here, we will dive a bit deeper into the differences between limitations and delimitations and provide some helpful tips for addressing them in your research project—whether you common dissertation limitations working on a quantitative or qualitative study.
However, the biggest difference between limitations and delimitations is the degree of control you have over them—that is, how much common dissertation limitations are based in conscious, intentional choices you made in designing your study.
Some limitations are inherent to your research design itself. Likewise, common dissertation limitations, while an experimental study allows you to draw causal conclusions, it may require a level of experimental control that looks very different from the real world thus lowering external validity.
Of course, your choice of research design is within your control; however, the limitations of the design refer to those aspects that may restrict your ability to answer the questions you might like to answer, common dissertation limitations. Limitations can get in the way of your being able to answer certain questions or draw certain types of inferences from your findings, common dissertation limitations.
Delimitations are also factors that can restrict the questions you can answer or the inferences you can draw from your findings. However, they are based on intentional choices you make a priori i. Like limitations, delimitations are a part of every research project, and common dissertation limitations is not a bad thing. If you try to do so, common dissertation limitations, your project is bound to get huge and unwieldy, common dissertation limitations, and it will become a lot more difficult to interpret your results or come to meaningful conclusions with so many moving parts.
You have to draw the line somewhere, and the delimitations are where you choose to draw these lines. One of the clearest examples of a delimitation that applies to almost every research project is participant exclusion criteria.
In conducting either a quantitative or a qualitative study, you will have to define your population of interest. Defining this population of interest means that you will need to articulate the boundaries of that population i. Those boundaries are delimitations.
The possibilities can go on. These are choices you will need to make, both for practical reasons i. Or parents. Or elementary school children. As interesting as their experiences might be, you can save these questions for another study.
That is the part of the beauty of research: there will common dissertation limitations be more studies to do, more questions to ask. Similarly, the focus of the research problem itself and the associated research questions is another common source of delimitations. By choosing to focus your research on a particular problem or question, you are necessarily choosing not to examine other problems or questions, common dissertation limitations.
There may be other related problems or questions that common dissertation limitations equally worthy of study, common dissertation limitations, but you must choose which one s you are and which ones you are not looking into with common dissertation limitations project.
For instance, you are not asking how effective the new curriculum is in improving student test scores or graduation rates. You might think that would be a very interesting question, but it will have to wait for another study. These other questions may be interesting and important, but, again, they are beyond the scope of your project.
While each study will have its own unique set of limitations, some limitations are more common in quantitative research, and others are more common in qualitative research, common dissertation limitations.
As noted above, the two most common sources of delimitations in both quantitative and qualitative research include the following:.
Because these questions define the boundaries or scope of your project and thus point to its delimitations, your research design itself will also be related to these delimitations. As you are considering the limitations and delimitations of your project, it can be helpful to ask yourself a few different questions. If I had an unlimited budget, unlimited amounts of time, access common dissertation limitations all possible populations, and the ability to manipulate as many variables as I wanted, how would I design my study common dissertation limitations to be better able to answer the questions I want to answer?
The ways in which your study falls short of this will point to its limitations. Do I have concerns about participants telling the truth or being able to provide accurate responses to my questions? What are my exclusion criteria?
Who did I not include in my study, and why did I make this choice? What questions did I choose not to address in my study? Of course, the possibilities are endless here, but consider related questions that you chose not to address. In what ways did I narrow the scope of my study in order to hone in on a particular issue or question?
What other methodologies did I not use that might have allowed me to answer slightly different questions about the same topic? Remember, having limitations and delimitations is not a bad thing. The important thing is to be aware of them and to acknowledge how they may impact your findings or the conclusions you can draw, common dissertation limitations. In fact, writing about them and acknowledging them gives you an opportunity to demonstrate that you can think critically about these aspects of your study and how they impact your findings, even if they were out of your control, common dissertation limitations.
Good, strong research projects have clear boundaries. Also, keep in mind that you are the researcher and you can choose whatever delimitations you want for your study. You just have to be prepared—both in your discussion section and in your dissertation defense itself—to justify the choices you make and acknowledge how these choices impact your findings.
