Consider a scenario in which a highly selective school wanted to improve its selection of prospective students. A consultant developed a new predictor with an internal consistency reliability of .75. The consultant then correlated the new measure with a criterion of student success, and found that the resulting correlation was .39. Prior to reporting the results, the consultant considered whether corrections for attenuation due to unreliability should be performed in the predictor, the criterion, neither, or both. Provide a recommendation explaining how the consultant should proceed.
