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.
