You must clearly describe what you wish to learn as well as what you do not intend to study. Make sure to be very explicit in both areas so that your reader understands your objective on both levels. Limitations, on the other hand, are the factors that will impact your study's capacity to generalize its findings. For example, if you were studying flowers, you would want to make sure that you include all varieties in your sample, male and female, wild and cultivated.
Limitations can also be described as factors that may affect the validity of the study. For example, if you were studying how much money people spend at McDonald's, you would want to make sure that you did not sell food at the research site or offer any free samples. This might influence what people buy and could therefore affect your results.
Finally, limitations can be personal factors such as gender, age, race, or ethnicity. If these characteristics are not taken into account, your study may have biased results.
Limitations should always be stated explicitly in studies so that readers understand why certain conclusions may be drawn from the data collected.
We recommend breaking down your limits section into three steps: (1) identify the limits; (2) describe how they effect your work; and (3) suggest a future research path and alternatives. For example, if one of your limitations is lack of funding, then you could mention other studies that have been funded and what they revealed about the relationship between attachment style and psychopathy.
Limitations are important aspects of any study that need to be considered when interpreting results and planning future investigations. In order to make sure that these limitations are not overlooked when writing up your study, it is best to include them in your thesis itself. Here are two ways of doing this:
First, you can list your limitations directly after your introduction. For example, one study that looked at the link between attachment style and psychopathy over time would include the following information: "One limitation of this study is that we were only able to examine psychopathy using self-report measures, rather than interviewing participants or observing them in therapy sessions."
Second, you can mention limitations throughout your paper, even where it isn't necessary to do so. For example, you could say something like the following: "Another limitation of this study is that we did not measure intelligence or socioeconomic status", instead of repeating the explanation in the text every time such a limitation is discussed.
The study's limits are those aspects of design or technique that impacted or influenced the interpretation of your research's findings. For example, a clinical trial may be limited by factors such as small sample size, short duration, or selectivity of patient population. When interpreting results from a study that was not designed to answer your specific question, it is important to consider these limitations.
Literature reviews also have limits related to the available evidence. Because most studies needed for a systematic review are published in scientific journals, there is a risk that only published data will be included in the review. In addition, because literature reviews often use explicit criteria to select studies for inclusion in the review, they are susceptible to bias due to subjectivity of the selection process. Finally, because of time constraints and limited resources, many literature reviews focus on a small number of topics within broad categories (e.g., cancer screening), which may limit the availability of information about interventions or conditions relevant to certain populations of interest.
First, consider what information you need from the literature before you begin writing your review. Do you need general background information about a topic?
