Modeling Item Response Times with a Two-State Mixture Model: A New Method of Measuring Speededness.
Schnipke, Deborah L.; Scrams, David J.
Journal of Educational Measurement, v34 n3 p213-32 Fall 1997
A method to measure speededness on tests is presented that reflects the tendency of examinees to guess rapidly on items as time expires. The method models response times with a two-state mixture model, as demonstrated with data from a computer-administered reasoning test taken by 7,218 examinees. (SLD)
