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:
Author, A. A. (Year). Title of data set (Version number) [Data set]. Publisher or Source. DOI or URL.
Here are some examples:
