Abstract | Item-discrimination indices are numbers calculated from test data that are used in assessing the effectiveness of individual test questions. This article asserts that the indices are so unreliable as to suggest that countless good questions may have been discarded over the years. It considers how the indices, and hence overall test reliability, are affected by guessing and question complexity. (EV) |
