Sensitivity of Group Job Descriptions to Possible Inaccuracies in Individual Job Descriptions. Interim Report, 1 Jan 73-31 Dec 73.
Carpenter, James B.
This study was designed to determine the relative impact of dichotomized task performance data compared to percent time-spent estimates for those members performing each task on the group job descriptions determined through application of the Comprehensive set of Occupational Data Analysis Programs (CODAP). Using groups identified by a routine application of the CODAP system, the percent members performing vector was found to correlate in the mid to high 90's with the percent time spent by a total group vector or group job description. These findings suggest that in groups of five or more individuals, dichotomized task performance data, which has previously been shown to have high reliability and validity, is the most critical component in the resultant group job description. Further possible time-spent inaccuracies in individual job descriptions would not be expected to cause major changes in the group job description since its unique contribution accounts for effectively less than 10 percent of the total variance. These results are consistent across different sized groups of varying homogeneity. This report will be of interest only to those agencies engaged in occupational data analyses employing the CODAP system. (Author)
