An educational scientist wants to examine the correlation between years of education and job satisfaction. To address this question, the scientist recruits a group of participants and has each complete a self-administered survey; the first question asks how many years of education the participant has (e.g., 12 = high school diploma, 14 = associate's degree, 16 - bachelor's degree, 18 - masters degree). The remaining question consists of the Acme Job Satisfaction Index (AJSI), which produces a score between O and 60 (0 = very unsatisfied, 60 = very satisfied with job)
