Statistical Information

Statistical information often serves as persuasive evidence, because it provides a good way of measuring trends and identifying factors that are related to each other without relying on individual cases. However, you should always make sure that you understand how the statistics that you are using were gathered. Pay attention to the sample size and how members of that sample were selected.

If you need a quick fact, there are several books in our reference section on Level 3 you may want to consult, including The World Almanac and Book of Facts.

Longer and more detailed requests for statistical information, such as the census, may require you to search statistical websites and databases online. Here is a list of useful sources of statistical information. Several of them are provided by the United States government, which maintains some good sources for statistical data on the Web.
