Tests for the selection of inspector-packers

Abstract

"The duties of the inspector-packers [in a pharmaceutical supply house] consisted of (1) filling capsules, vials, and bottles with serums, antitoxins, and similar biologicals, (2) stoppering the containers, (3) examining them for the presence of extraneous foreign material, (4) labeling them, and (5) cartoning and packaging them. A combination of the ratings of the supervisor and forelady was used as the criterion of job proficiency of the 26 girls who were studied. Several tests were administered… and the following validity coefficients were obtained: Minnesota Paper From Board, .57; peg board, -.50; Minnesota Rate of Manipulation-Turning, -.40; Minnesota Rate of Manipulation-Placing, -.24; Minnesota Vocational Test for Clerical Workers-Number Comparison, .29; Minnesota Vocational Test for Clerical Workers-Name Comparison, -.26; and the MacQuarrie Test for Mechanical Ability, .19." The Wherry test selection method selected the Paper Form Board, the peg board, and the MacQuarrie copying and dotting items, in the order named, and yielded a shrunken r of .72 with the criterion. "In practice the Paper Form Board and the Rate of Manipulation tests are being employed." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
