To assess the workplace benefits of providing paid time off (PTO), the Human Resources (HR) Department implements and evaluates different PTO plans at each of the company’s three sites: Site 1 will serve as the control group; employees at this site will continue to receive 2 weeks of PTO per year. Employees at Site 2 will receive 2 weeks of PTO per year plus the fourth Friday of each month off (with pay). Employees at Site 3 will receive 3 weeks of PTO per year. The HR Department will use a web-based survey to gather the following data from all employees: Score on the Acme Morale Scale (1 = Extremely low morale . . . 25 = Extremely high morale). Additionally, seniority (the number of years at the company) will be recorded (as the covariate).
