Are statistics consistent with those you encounter in other sources? Have they been used fairly? Does the author explain where the statistics come from? (It is possible to “lie” with statistics by using them selectively or by omitting mathematical details.)
Does the Web site or document have an author? You may need to do some clicking and scrolling to find the author’s name. If you have landed directly on an internal page of a site, for example, you may need to navigate to the home page or find an “about this site” link to learn the name of the author.
If there is an author, can you tell whether he or she is knowledgeable and credible? When the author’s qualifications aren’t listed on the site itself, look for links to the author’s home page, which may provide evidence of his or her interests and expertise.
What does the URL tell you? The domain name extension often indicates the type of group hosting the site: commercial (.com), educational (.edu), nonprofit (.org), governmental (.gov), military (.mil), or network (.net). URLs may also indicate a country of origin: .uk (United Kingdom) or .jp (Japan), for instance.
