Higher Validity in the Face of Lower Reliability: Another Look.
Frary, Robert B.
Applied Measurement in Education, v13 n3 p249-53 2000
Characterizes the circumstances under which validity changes may occur as a result of the deletion of a predictor test segment. Equations show that, for a positive outcome, one should seek a relatively large correlation between the scores from the deleted segment and the remaining items, with a relatively low correlation between scores from the deleted segment and the criterion.
