Irt based method

WebItem response theory (IRT) is another widely used method for assessing DIF. IRT allows for a critical examination of responses to particular items from a test or measure. As noted earlier, DIF examines the probability of correctly responding to or endorsing an item conditioned on the latent trait or ability. In psychometrics, item response theory (IRT) (also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables. It is a theory of testing … See more The concept of the item response function was around before 1950. The pioneering work of IRT as a theory occurred during the 1950s and 1960s. Three of the pioneers were the Educational Testing Service See more The IRF gives the probability that a person with a given ability level will answer correctly. Persons with lower ability have less of a chance, while persons with high ability are very likely to answer correctly; for example, students with higher math ability are more … See more One of the major contributions of item response theory is the extension of the concept of reliability.
