Summary

The purpose of this study was to determine whether option weighting improved the internal consistency and intercorrelation of the subtests. The differential option-weighting scheme employed in this study is based on one devised by Guttman. The tests were first scored with Guttman-type weights and then with conventional correction-for-guessing weights. The internal-consistency of the tests increased markedly when Guttman-type weights were used. The correlation of the two verbal subtests increased somewhat when Guttman weights were used, but the correlation of the two mathematics subtests as well as the intercorrelation of all verbal and mathematics subtests decreased. Differences in the factor structure of the Guttman-weighted and the conventionally weighted subtests were used to explain the result. (Author)
