Data used in aggregate to perform analysis that will support decision-making, such as program evaluation, comparison, or research. Analytic data may have been collected primarily for analytic functions (e.g. survey data) or may have been collected primarily for other purposes (e.g. administrative data). Data becomes analytical data when it is used for analytical purposes. In other words, a piece of data may have initially been collected and used for administrative functions but becomes analytical data when it is used as an input to an analysis.
