Dr. Gorman is an industrial/organizational psychologist who is interested in variables that are important for job productivity. She believes that the number of hours a person spends engaged in cardiovascular exercise each week is linked to job productivity. To examine this issue, she identifies 500 employees at a manufacturing plant for cellphones. Her primary hypothesis is that the more hours per week someone engages in cardiovascular exercises, the more productive they are in their job. She has all 500 employees complete a survey questionnaire that assesses their exercise behaviors and includes questions that allows her to determine how many hours per week they spend engaging in cardiovascular exercise activities. During the week the employees complete the survey, Dr. Gorman also assesses their work productivity by measuring how many cellphones each person produces during the entire week. She then examines the relationship between number of hours of cardiovascular exercise reported and number of cellphones produced per week
