Aggregating Scores: To Standardize or Not to Standardize?
Gardner, R. C.; Erdle, S.
Educational and Psychological Measurement, v44 n4 p813-21 Win 1984
This paper demonstrates that, although aggregated standard scores can correlate substantially with aggregated raw scores, their correlations with an external criterion can differ markedly. This will occur when the variances of the components differ, and these differences are related to the correlations of the components with the criterion. (Author)
