Phys. Rev. ST Physics Ed. Research 5, 020103 (2009) [17 pages]Approaches to data analysis of multiple-choice questions
This paper introduces five commonly used approaches to analyzing multiple-choice test data. They are classical test theory, factor analysis, cluster analysis, item response theory, and model analysis. Brief descriptions of the goals and algorithms of these approaches are provided, together with examples illustrating their applications in physics education research. We minimize mathematics, instead placing emphasis on data interpretation using these approaches. This article is available under the terms of the Creative Commons Attribution 3.0 License.
