Webit known. The most distinct feature of IRT is that is adopts explicit models for the probability of each possible response to a test—so its alternative name, probabilistic test theory, may be the more apt one. IRT derives the probability of each response as a function of the latent trait and some item parameters. The same model is then used ... WebThe ICC curve is essentially a curve for an item \(j\) that plots the relationship between \(\theta\): ability of examinee; and \(P_j(\theta)\): probability of answering \(j\) correctly. As ability changes, probability of correct response also changes. The ICC shows how it changes. What we want to do next is to draw ICCs for each GRE40 item. greenfield community school newton aycliffe
