Data Visualization: Developing and Validating Dashboard Measurement Instruments

Data analytics literature has not adequately addressed the empirical investigation of dashboard evaluations. Instruments that measure the dashboard dimensions and usefulness are yet to be proposed. This research is geared toward this end. The objective is to examine the theoretical underpinnings of data visualization using dashboards, to develop and validate an instrument for the measuring of dashboard usefulness in the public sector. Data collected from 160 dashboards of public or government institutions were used to validate a measurement model using structural equation modeling. PLS (Partial Least Squares) techniques and the SPSS software were used to assess the model and measures. Theoretical and practical implications are offered.
