The scoring method proposed here provides advantages of grading "on a curve" such as the ability to estimate and compare the complexity of different concept maps, the ability to measure the statistical distance between individual map scores, the ability to define map-score quantiles, a reduction in grading bias, and an overall improvement in the reliability and validity of concept map evaluation.
Among their topics are statistical distances, measures of robustness and computational issues, weighted likelihood estimation, the density power divergence, and distance measures in information and engineering.
