Measures of Discrimination Among Achievement Levels in Statistics.
Huberty, Carl J.; Smith, Douglas U.
Eight discriminators were identified and data were obtained from the records of 80 graduate students who attained one of four achievement levels at the conclusion of a beginning course in educational statistics. Although the internal discriminatory power of the set of eight measures was very high, estimates of the true power were discouragingly low. Two GRE measures were judged to be the best discriminators, but very poor when considered alone or in combination. Prediction for the second achievement level appeared fairly strong, even for an external analysis. Linear as well as quadratic classification results are included. (Author)
