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…

A procedure is described for increasing the reliability of tests after they have been given and for developing shorter but more reliable tests. Eight tests administered to 200 graduate students studying educational research are analyzed. The analysis considers the original tests, the items loading on the first factor of the test, and the items…
