Deep dives
Introduction to Item Response Theory (IRT)
Item response theory (IRT) is introduced as a modern statistical approach that addresses some limitations inherent in classical test theory. IRT focuses on the relationship between an individual's latent traits and their item responses, offering a framework for understanding how test items function across different levels of ability. This model allows researchers to assess item difficulty and the effectiveness of individual items for discriminating between varying ability levels. By examining the probability of a correct response, IRT enhances the understanding of measurement properties in assessments.
