The researcher may treat highly correlated criteria in several different ways. He or she may
choose to drop one of the criteria, viewing it essentially as redundant information, or to keep the
two criterion measures separate, reasoning that the more information collected, the better.
A third strategy is to gather data relevant to both criterion measures, to convert all data to standard
score form, to compute the individual's average score, and to use this as the best estimate of
the individual's standing on the composite dimension. No matter which strategy the researcher
adopts, he or she should do so only on the basis of a sound theoretical or practical rationale and
should comprehend fully the implications of the chosen strategy.
