Scenario:
Employers seek ways to improve the performance of their employees. Gardner, Van Dyne, and Pierce (2004) hypothesized that performance is influenced by organizational self-esteem, defined as an employee’s evaluation of his or her personal adequacy as an organizational member. More specifically they hypothesized that the higher one’s organizational self-esteem, the higher will be one’s job performance. The data below (representative of the study’s findings) represent the employees’ job performance level on a scale from 1 (low performance) to 5 (high performance). Determine whether job performance varies as a function of organizational self-esteem.
