If item misfit with any model is diagnosed as due to poor item quality, for example confusing distractors in a multiple-choice test, then the items may be removed from that … See more Classical test theory (CTT) and IRT are largely concerned with the same problems but are different bodies of theory and entail different … See more Broadly speaking, IRT models can be divided into two families: unidimensional and multidimensional. Unidimensional models require a single trait (ability) dimension See more One of the major contributions of item response theory is the extension of the concept of reliability. Traditionally, reliability refers to the … See more The person parameter $${\displaystyle {\theta }}$$ represents the magnitude of latent trait of the individual, which is the human capacity or attribute measured by the test. It might be … See more
