| Abstract: | D unér , A. & M agnusson , D. A formula for the use of suppression variables in correcting individual ratings. Scand. J. Psychol , 1962, 3 , 226–232.—Ratings of aptitude, ability or performance used for selection and/or prediction or as criteria for the estimation of the validity of other methods are often influenced by irrelevant factors. Two correction formulas based on a suppression variable have been derived. The relation between the correlation formula derived and the partial correlation formula is discussed, as well as the effect of the application of the formula on the estimation of differential validity. |
