For example, the book is currently rated about 4.5 stars on amazon.com. <ref>http://www.amazon.com/How-Lie-Statistics-Darrell-Huff/dp/0393310728</ref> Using the book's method, the five questions can be answered accordingly (in the same order):
  −
:*Amazon.com claims the book is rated 4.5 "stars".
  −
:*The source has gathered ratings from anonymous buyers of the book.
  −
:*There is not sufficient evidence that all the ratings are posted legitimately.
  −
:*The subject has not been changed, but assumptions have been made about the ratings' authors.
  −
:*The ratings seem to vary in quality enough to be considered legitimate at a glance.
