This classic volume outlines, for both students and professionals,
the mathematical theories and equations that are necessary for
evaluating a test and for quantifying its characteristics. The
author utilizes formulas that evaluate both the reliability and the
validity of tests. He also provides the means for evaluating the
reliability and validity of total test scores and individual item
analysis. The work remains one of the only books on classical test
theory to discuss applications, "true score" theory, the effect of
test length on reliability and validity, and the effects of
univariate and multivariate selection on validity.
