Data Quality: Earning the Confidence of Decision Makers.
Ligon, Glynn D.
Professionals responsible for educational research, evaluation, and statistics have sought to provide timely and useful information to decision makers. Regardless of the evaluation model, research design, or statistical methodology employed, informing the decision making process with quality, reliable data is a basic goal. The definition of quality for education data has not been adequately addressed in the literature of educational research and evaluation. In the publications describing quality related to general information systems, the concept is narrowly interpreted to mean accurately and reliably processed data. This paper ties together the foundations of data quality from the formal information systems literature with the practical data quality in the arena of public education decision making. A hierarchy of data quality is described to assist both the understanding of quality and the requirements for achieving quality. The hierarchy ranges from the availability of dysfunctional, bad data to the quality level of data-based decisions made with confidence. For practitioners, a checklist is provided for use in determining the quality of their data sources. Attachments include the data quality typology, a list of ratings of data quality, and the checklist for rating and improving data quality. (Author/SLD)
