Criterion-Related Validity of Composite Scores Based on the Highest (or Smallest) ObservationsUniversity of South Carolina Under the assumption of normality, a formula is derived for criterion-related validity of a partial composite score based on the highest (or lowest) of several equivalent observations. This partial composite score has higher validity than each single observation. However, it has less validity than the composite score based on all observations.
