Generalizability theory proposes that sources of systematic error (such as method, rater, and occasion effects) are separated from random error in order to minimize systematic error and increase the generalizability of results. Classical test theory and reliability theory primarily focus on measuring reliability and validity, while the theory of the normal curve is a statistical theory that describes the distribution of data.
