WebJul 24, 2024 · The IRT serves as a framework for which scaled scores are computed. As mentioned earlier, this theory is focused on the probability that a test-taker will answer an item correctly. One of the methods in determining the test-takers’ scores in an IRT-based test is “pattern scoring.” WebJul 13, 2016 · Choose sum-score based EAP scoring. The very bottom gives the marginal reliability given the properties of the items (and thus independent from your sample). Marginal reliability and the associated SEM is one way to get at a one-number summary using IRT-based statistics.
