Support your position in a paper with data. This can be an effective way to back up your claims and strengthen your argument. Be sure, however, to present the data in a clear and easy to understand way. Do not create graphs or tables that are excessively complicated and be sure to provide a legend, headings, or notes to clarify aspects of the graph which aren't obviously understandable. If you include data, make sure that you comment upon it. It's best to focus on the most important takeaway from the data than to go into excessive detail about every data point.
