ITEM ANALYSIS BASED ON CONFIDENCE RESPONSES,
Abstract
In examining the behavior of a group of subjects with respect to one test item, a distribution of confidence is obtained for each answer to the item. Empirical confidence distributions are analyzed for the responses of 98 students to 16 four-alternative items. Techniques are derived for computing both a difficulty index and a validity index from confidence data. Two graphical techniques are devised and applied to 16 items to indicate the ability of these items to discriminate between the better and poorer students. One graphical technique compares the confidence distributions for each of the possible answers for the upper and lower subjects while the other technique compares the frequency of occurrence of various states of knowledge in the upper and lower groups.
