Explore the ICPSR Web site. Start by browsing their list of subject headings and then writing a short summary of the datasets available about one subject. You can start at http://www.icpsr.umich.edu/.

Try an online analysis. Go to one of the Web sites that offer online analysis of secondary data, like the ICPSR site. Review the list of variables available for online analysis of one dataset. Now form a hypothesis involving two of these variables, request frequency distributions for both, and generate the crosstab in percentage form to display their relationship.
