Efficiency plus economy in scoring an interest test

Description
Summary:A study designed to test the effects of using Kelley's new formula for weighting items ( J. educ. Psychol. , 1934, ^W25^n, 504-510) on the Strong vocational interest blank, and to test the effect of reducing the range of scoring weights from 31 to 9. The interest blank data obtained from 100 engineers, 100 chemists, 100 life-insurance salesmen, 100 lawyers, and 100 ministers were used. The results suggest that the two formulae and the two ranges of weights may be used interchangeably in differentiating between occupations, even though some conditions may conceivably make the new formula extremely advantageous. The use of the new formula and the restricted range of weights is recommended for adoption as standard procedure.
