The Internet is a great place to find statistics and data! However, it is important to evaluate that information before citing it in a paper. An easy way to find credible statistics and data is to limit your searches to government or educational websites. You can do this by performing an advanced search in Google or by adding :.gov or :.edu to the end of your search terms in Google. If you are using articles or websites that reference data or reports but did not conduct the original research, make sure you can get back to the original research or data set which is hopefully referenced in the article or website.
By adding the .gov limit to my search I only see government websites in my results, which hopefully ensures credibility.
