The validity coefficient for a college admissions test for predicting freshman year GPA is .40. The test's reliability is .80. If we apply the correction for unreliability in this situation, the validity coefficient will ___.

Question

Quizplus · Accepted Answer

The correction for unreliability formula is used to estimate the true validity by accounting for measurement error in the predictor (test scores). The formula is: corrected validity = observed validity / sqrt(reliability). Given the observed validity (.40) and reliability (.80), applying the correction formula would result in an increase in the validity coefficient, as the denominator (sqrt(.80)) is less than 1, thus increasing the value of the observed validity when divided by it.
