AN ITEM ANALYSIS WHICH TAKES INDIVIDUAL DIFFERENCES INTO ACCOUNT 论文

摘要

An approach to item analysis is described by means of which the difficulty of an item and the ability of an individual may sometimes be assessed without reference to the norms provided by some population. The model employed in the analysis could also be used to study any situation in which a number of subjects perform a series of tasks having the same two alternative responses. Some particular uses of the model are discussed briefly.
