Citing Data and Statistics
Whether you use a numeric dataset or a prepared statistical table from an existing source (print or electronic) you need to cite the source of your information. Depending on the citation style you're required to use for your work it could look like one of the following:
United States Census Bureau. (2000). Census 2000 summary file 3: Maryland raw data. Retrieved 6/5/2010 from http://www2.census.gov/census_2000/datasets/Summary_File_3/Maryland/.
Pew Internet and American Life Project. (2010). Demographics of internet users. Retrieved 6/5/2010 from http://www.pewinternet.org/Trend-Data/Whos-Online.aspx.
