A Chi-Square Approach to Discrimination Among Occupations, Using an Interest Inventory.
Porter, Andrew C.
In a rapidly changing technological society, appropriate choice of occupation becomes increasingly important to the individual as well as to the employer. In this study, the effectiveness of a set of weights, established by the chi-square technique, for distinguishing among similar and dissimilar occupations was compared with the weighting scheme for the Kuder Preference Record Occupational Form D. Data were scored by both sets of weights to determine the percentage of males correctly classified according to occupation by each weighting scheme. The findings indicate that the chi-square weights are superior to the Kuder weights for distinguishing among similar occupations: optometrist, pediatrician, veterinarian, physical therapist, and X-ray technician. The total number of subjects in similar occupations was 1,902. An improper scoring key was used to determine the percentages which were based on Kuder weights for dissimilar occupations; therefore the findings for dissimilar occupations were discounted. The dissimilar occupations were clinical psychologist, social case worker, optometrist, forester, and auto mechanic. Double cross-validation studies of the chi-square derived weights indicate that they are general in nature and not just indicative of the sample upon which the present study was based. (CH)
