Assignment Students in an introductory psychology course were asked to participate in an experiment examining the relationship between quality of sleep and perceived stress. Each student in the class kept track of the quality of his or her sleep for seven consecutive days using a 5-point scale where 1 indicated very poor quality. 3 indicated average quality, and 5 indicated excellent sleep quality for the previous night. At the end of the week, each student donated a small hair sample consisting of approximately 20 to 30 strands of hair. The level of cortisol in the hair sample was obtained [in nanograms per gram of hair). Higher levels of cortisol indicate higher levels of stress. The table below shows the raw data from the 50 students in the study.
