Empirical Keying of Biographical Data: Cross-Validity as a Function of ScalingProcedures and Sample Size. (Reannouncement with New Availability Information)

摘要

In recent years, the military has devoted considerable effort to the developmentof empirically keyed biodata instruments for use in selection. Although studies using empirical keying procedures are common in the personnel selection literature, relatively few studies have compared these procedures. Using data collected from Naval Academy midshipmen, we compared nine empirical keying procedures: vertical percent (five strategies), horizontal percent, mean criterion, phi coefficient, and rare response. For each keying procedure, five different sample sizes were used to determine the minimum sample size needed to obtain stable results. For the three largest samples, all of the criterion-based methods yielded scales with significant cross-validities. Among these methods, two vertical percent strategies generally produced the most valid scales for the four largest samples. Without exception, the cross-validities for the only noncriterion-based method (rare response) failed to reach significance. The effects of unit versus differential weighting and scale length versus item-alternative validity are discussed.... Biodata, Navy recruits, Weighting procedures
