"Figures often beguile me, particularly when I have the arranging of them myself; in which case the remark attributed to Disraeli would often apply with justice and force: 'There are three kinds of lies: lies, damned lies and statistics.'" 

Mark Twain's Own Autobiography: The Chapters from the North American Review

Citing data and statistics allows writers to credit data creators and allows readers to find and verify the context of information. 

No matter which citation style you are using, the basic elements remain the same. Citations communicate—

• Who- Identify what person or organization is responsible for the information
• When- Indicate the date of publication
• What- Provide the full title of the document or content including any subtitle, version number, or report number
• Where- Include the source basics needed to locate the information; distributor or publisher info (the journal title, book publisher, or website publisher), the URL or DOI if accessed online, and a retrieval date when needed
