Data and statistics require citations for the same reasons journal articles and other types of publications require citations: to acknowledge the original author/producer and to help other researchers find the resource.
Some style manuals provide instructions for the citation of data. Be sure to follow the general citation format for the style manual your professor has asked you to use. It is always better to provide more information about a resource rather than less!
These are the citation elements you need to consider:
Author: Who is the creator of the data set? This can be an individual, a group of individuals, or an organization.
Title: What name is the data set called, or what is the name of the study?
Edition or Version: Is there a version or edition number associated with the data set?
Date: What year was the data set published? When was the data set posted online?
Editor: Is there a person or team responsible for compiling or editing the data set?
Publisher and/or Distributor: What entity is responsible for producing and/or distributing the data set? Also, is there a physical location associated with the publisher?
In some cases, the publisher of a data set is different than how we think of the publisher of a book. A data set can have both a producer and a distributor.
The producer is the organization that sponsored the author’s research and/or the organization that made the creation of the data set possible, such as codifying and digitizing the data.
The distributor is the organization that makes the data set available for downloading and use.
You may need to distinguish the producer and the distributor in a citation by adding explanatory brackets, e.g., [producer] and [distributor].
Some citation styles (e.g., APA) do not require listing the publisher if an electronic retrieval location is available. However, you may consider including the most complete citation information possible and retaining publisher information even in the case of electronic resources.
Material Designation: What type of file is the data set?
For example, is it on CD-ROM or online?
This may or may not be a required field depending on the style manual. Often this information is added in explanatory brackets, e.g. [computer file].
Electronic Location or Identifier: What web address is the data set available at? Is there a persistent identifier available?
If a DOI or other persistent identifier is associated with the data set it should be used in place of the URL.
