2. Go to the Roper Center for Public Opinion Research website at https://ropercenter.cornell.edu. Now, pick the presidential approval ratings data at https://presidential.roper.center.

Based on poll data on presidential job performance, create a brief report that includes the following for each president you chose: the presidents you chose and their years in office; the question asked in the polls; and bar charts showing years when polls were taken, average of total percentage approving of job performance, average of total percentage disapproving of job performance, and average of total percentage with no opinion on job performance. Write a brief summary comparing and contrasting your two bar charts.
3. Do a Web search for information on a social science subject in which you are interested. About what fraction of the information you find relies on statistics as a tool for understanding the subject? How do statistics allow researchers to test their ideas about the subject and generate new ideas? Write your findings in a brief report, referring to the websites you used.
