Stating the Obvious: Writing Assumptions, Limitations, and Delimitations - PhDStudent
During the process of writing your thesis or dissertation, you might suddenly realize that your research has inherent flaws. Virtually all projects contain restrictions to your research. However, being able to recognize and accurately describe these problems is the difference between a true researcher and a grade-school kid with a science-fair project. Concerns with truthful responding, access to participants, and survey instruments are just a few of examples of restrictions on your research.
In the following sections, the differences among delimitations, limitations, and dissertation limitations and delimitations of a dissertation will be clarified. Delimitations are the definitions you set dissertation limitations and delimitations the boundaries of your own thesis or dissertation, so delimitations are in your control. Delimitations are set so that your goals do not become impossibly large to complete.
Examples of delimitations include objectives, research questions, dissertation limitations and delimitations, variables, theoretical objectives that you have adopted, and populations chosen as targets to study. When you are stating your delimitations, clearly inform readers why you chose this course of study. In any case, you should clearly list the other options available and the reasons why you did not choose these options immediately after you list your delimitations. You might have avoided these options for reasons of practicality, interest, or relativity to the study at hand.
For example, you might have only studied Hispanic mothers because they have the highest rate of obese babies. Delimitations are often strongly related to your theory and research questions, dissertation limitations and delimitations.
If you were researching whether there are different parenting styles between unmarried Asian, Caucasian, African American, and Hispanic women, then a delimitation of your study would be the inclusion of only participants with those demographics and dissertation limitations and delimitations exclusion of participants from other demographics such as men, married women, and all other ethnicities of single women inclusion and exclusion criteria, dissertation limitations and delimitations.
A further delimitation might be that you only included closed-ended Likert scale responses in the survey, rather than including additional open-ended responses, which might make some people more willing to take and complete your survey. Remember that delimitations are not good or bad. They are simply a detailed description of the scope of interest for your study as it relates to the research design.
Limitations of a dissertation are potential weaknesses in your study that are dissertation limitations and delimitations out of your control, dissertation limitations and delimitations, given limited funding, choice of research design, statistical model constraints, or other factors. In addition, a limitation is a restriction on your study that cannot be reasonably dismissed and can affect dissertation limitations and delimitations design and results.
Do not worry about limitations because limitations affect virtually all research projects, as well as most things in life. Even when you are going to your favorite restaurant, you are limited by the menu choices.
If you went to a restaurant that had a menu that you were craving, you might not receive the service, dissertation limitations and delimitations, price, or location that makes you enjoy your favorite restaurant. The people whom you managed to get to take your survey may not truly be a random sample, which is also a limitation.
If you used a common test for data findings, your results are limited by the reliability of the test. If your study was limited to a certain amount of time, your results are affected by the operations of society during that time period e.
It is important for you to remember that limitations of a dissertation are often not something that can be solved by the researcher. Also, remember that whatever limits you also limits other researchers, whether they are the largest medical research companies or consumer habits corporations, dissertation limitations and delimitations. Certain kinds of limitations are often associated with the analytical approach you take in your research, too.
For example, some qualitative methods like heuristics or phenomenology do not lend themselves well to replicability. Also, most of the commonly used quantitative statistical models can only determine correlation, but not causation.
Assumptions are things that are accepted as true, or at least plausible, by researchers and peers who will read your dissertation or thesis. In other words, any scholar reading your paper will assume that certain aspects of your study is true given your population, statistical test, research design, or other delimitations.
Because most assumptions are not discussed in-text, assumptions that are discussed in-text are discussed in the context of the limitations of your study, which is typically in the discussion section. This is important, because both assumptions and limitations affect the inferences you can draw from your study. One of the more common assumptions made in survey research is the assumption of honesty and truthful responses.
However, for certain sensitive questions this assumption may be more difficult to accept, in which case it would be described as a limitation of the study.
For example, asking people to report their criminal behavior in a survey may not be as reliable as asking people to report their eating habits. It is important to remember that your limitations and assumptions should not contradict one another. For instance, if you state that generalizability is a limitation of your study given that your sample was limited to one city in the United States, then you should not claim generalizability to the United States population as an assumption of your study.
Statistical models in quantitative research designs are accompanied with assumptions as well, some more strict than others. These assumptions generally refer to the characteristics of the data, such as distributions, correlational trends, and variable type, just to name a few.
Violating these assumptions can lead to drastically invalid results, though this often depends on sample size and other considerations, dissertation limitations and delimitations.

Thesis/Dissertation Tips #7: Limitations of Your Research
, time: 7:09Diving Deeper into Limitations and Delimitations - PhDStudent
Mar 28, · Any limitations that might influence the results should be mentioned. Delimitations are choices made by the researcher which should be mentioned. They describe the boundaries that you have set for the study. Assumptions are accepted as true, or at least plausible, by researchers and peers who will read your dissertation or thesis. More proposals and dissertations include a limitations section. Not including this section implies that your study has accounted for all (or nearly all) variables, is generalizable to all populations, and could be replicated accurately under all conditions.) Delimitations (Optional) Delimitations are factors that affect the study over which the research Oct 02, · The scope and delimitations of a thesis, dissertation or research paper define the topic and boundaries of the research problem to be investigated. The scope details how in-depth your study is to explore the research question and the parameters in which it
