A Study of Job Stress in Boundary-Spanning and Non-Boundary-Spanning Occupations (open access)

A Study of Job Stress in Boundary-Spanning and Non-Boundary-Spanning Occupations

This study tested the existence of significant differences in levels of perceived job stressors between non-managerial individuals in boundary-spanning and nonboundary- spanning occupations. Correlations between selected demographic characteristics and levels of perceived job stressors were also determined.

The Chi Square Approximation to the Hypergeometric Probability Distribution

This study compared the results of his chi square text of independence and the corrected chi square statistic against Fisher's exact probability test (the hypergeometric distribution) in contection with sampling from a finite population. Data were collected by advancing the minimum call size from zero to a maximum which resulted in a tail area probability of 20 percent for sample sizes from 10 to 100 by varying increments. Analysis of the data supported the rejection of the null hypotheses regarding the general rule-of-thumb guidelines concerning sample size, minimum cell expected frequency and the continuity correction factor. it was discovered that the computation using Yates' correction factor resulted in values which were so overly conservative (i.e. tail area porobabilities that were 20 to 50 percent higher than Fisher's exact test) that conclusions drawn from this calculation might prove to be inaccurate. Accordingly, a new correction factor was proposed which eliminated much of this discrepancy. Its performance was equally consistent with that of the uncorrected chi square statistic and at times, even better.
