WebbJust as Guttman before him, he also questioned the simplistic assumptions of CTT. Searching for alternatives, he developed a reliability theory that recognized several different types of measurement error—thus yielding several different types of reliability—to be analyzed within the framework of analysis of variance (generalizability theory).
