If you’re using a data set or a specialized kind of software or measurement tool, you should cite it in your reference list.
Of course you don’t have to cite common types of software such as Microsoft Word or Adobe Photoshop, nor do you have to account for the use of universal programming languages (e.g., Java).
Here is the basic format:
Rightsholder, A. A. (Year). Title of program (Version number) [Description of form]. Location: Name of Producer.
- You can often leave out the version number.
- If you can get the source online, then replace the location and publisher with a retrieval URL (Retrieved from URL).
- The description of form indicates the type of source we’re dealing with (e.g., data file, software, programming language, apparatus, training video).
- Italicize the names of data sets.
Brazilian Department of Soccer Statistics. (2007). Goal Scoring Efficiency of Forwards in a State of Post-Carnival Inebriation, 1999-2004 [Data Set]. Retrieved from https://brasiliasoccerfoundation.org/mental-health/datasets/
If the online source includes a DOI, you can provide that instead of the URL. For links to important data sets and repositories, check out this APA page.
HyperAware (Version 3.2) [Computer software]. Rushtown, CA: Caffeine Press.
For other measurement tools, simply adapt the basic format to your needs.
