three-parameter model

in item response theory, a model that specifies three parameters affecting an individual’s response to a particular test item: (a) the difficulty level of the item; (b) the discriminating power of the item; and (c) in multiple-choice items, the effect of guessing. The probability of a correct response to the item is held to be a mathematical function of these parameters.
