Probability-Based Inference in a Domain of Proportional Reasoning Tasks.
Beland, Anne; Mislevy, Robert J.
Probability-based inference is described in the context of test theory for cognitive assessment. Its application is illustrated with an example concerning proportional reasoning. The statistical framework is that of inference networks. Ideas are demonstrated with data from a test of proportional reasoning based on work by G. Noelting (1980). The observed data are comparisons of mixtures of juice and water made by 448 subjects (ranging from fourth graders through college freshmen), and their explanations of the strategies by which they arrived at their answers. The cognitive framework builds on A. Beland's structural analysis of the task component relationships involved in their solution strategies. Seven tables present observation data and relationships, and 11 figures illustrate the analysis. A 52-item list of references is included. (SLD)
