Data literacy is the ability to collect, manage, evaluate, and apply data, in a critical manner. It is a relatively new field of study, dating only from the 2010s. It includes the skills necessary to discover and access data, manipulate data, evaluate data quality, conduct analysis using data, interpret results of analyses, and understand the ethics of using data. This paper considers data literacy education across three frameworks: the competency model defining data literacy, the assessment of data literacy competencies, and methods for the development of data literacy in an organization. These principles are applied to a discussion of the development of an open online course supporting the development of data literacy in the form of a corresponding data structure encompassing the three frameworks identified in the literature.
