Be sure to think about your topic from different perspectives in order to avoid gaps in your analysis and identify other variables that might affect the results. One way to do this is to look at how other scholars have examined the same, or similar, research questions.
Obtaining data that fits your specific research needs is important. However, the perfect data may not be available to you. For example, you may not be able to find data that includes all of your desired variables or the date range might not be what you want. You should be wiling to adjust your research, if necessary. Can you accomplish your research with slightly different variables? Might you adjust your date range? If you are not able to accomplish your research objectives by altering data parameters you may need to adjust your research question.
