Infographics are a great way to visualize data; using images to tell a compelling story. However, don't be tempted by colorful images if the sources of data are not cited! Good infographics, like good research papers, acknowledge information sources. This example is posed on the American Heart Association website. It provides data on food deserts and cites the U.S. Department of Agriculture by name, but no web address is included for us to verify the data. A link to the full size infographic is here.

While conducting research on the web, it is imperative to evaluate the website in question for authority, documentation, currency, and bias. Doing so will ensure that you are using the most credible information possible to support your thesis.
Authority and Accuracy
Who produced the site? Are they a credible source? What is the purpose of the site? Why was it created? Is the person, organization, or group qualified to write this content? What is the domain of the URL?
Documentation
Is there adequate documentation for factual statements? Is the documentation reliable, verifiable from a second source? Is there enough information to cite this information in a paper (author, title, source, date)?
Currency
Is the information up to date? When was it created, or last edited? Are the links up to date or dead? Is the author using outdated statistics?
Objectivity and Bias
Is the document biased or slanted? Are there few or no logical errors such as appeal to authority or circular reasoning? If you found this information a printed source, would you trust it?
