This section should return you to the problem raised at the beginning of the paper. It provides the link between your narrow data analysis and the broader intellectual concerns with which you began. You might start by summarizing the results of your statistical tests and determining whether your research supported or contradicted prevailing theory. If you see weaknesses in your research, here is the place to comment and perhaps make suggestions about future research. I strongly advise against trying to collect your own data to write this paper.
Data collection is a time-consuming and often frustrating activity.
I would prefer that you spend your time in doing data analysis rather than data collection for this paper. You have several data sets from which to choose. You will probably consider different data sets before settling on one for your analysis. You will soon learn more powerful statistical techniques to employ in your analysis, which will make writing the paper more interesting.
