Abstract

Three models of human interactions with computer-displayed statistical graphics were developed and tested in an experiment which examined users' speed and accuracy on identification and comparison questions using 17 graph types. The results indicated that response time and accuracy were influenced by the perceptual and informational complexity of the graph, as well as the relation between the figure and axes, (Model 1); by the physical elements of the graph — points, lines, and areas (Model 2); and by the data-ink ratio and data density (Model 3). The discussion focuses on the development of a single integrated model of interactions with graphics.
