You work for HR in a medium-sized company with exactly 100 employees. The company recently collected supervisor-rated and coworker-rated job performance ratings for each of their employees. For the supervisor ratings, the supervisors were asked to rate each of their subordinate's job performance on a scale of 1 to 100. For the coworker ratings, the employees were asked to rate each of their coworker's job performance as either Bad, Okay, Good, or Great. The dataset includes each employee's supervisor-rated job performance as well as the most common response for their coworker-rated job performance.
