Using statistics to support a persuasive speech or research paper adds credibility and authority to your work. Organizations, both public and private collect and publish statistics.
One of the largest collectors of data and statistics is the U.S. federal government. Virtually every agency and department of government at every level collects statistics. To get started, think about how many agencies you know; for example the U.S. Census Bureau.
Using this guide, you will find statistics collected in books, databases, and websites. Visit the library for additional help, or use Ask-A-Librarian for online service.
