Question

How many dependent variables are represented in this chart? Explain how you determined this.

For many adolescents in high school, obtaining adequate sleep can be difficult. One proposed way to increase sleep duration for teens is to delay the school start time. In one study, the school schedule was modified. The study was conducted at a residential boarding school, where students lived at the school site rather than at home. For Fall term (Time 1), the schedule was 8am-6pm on Mondays, Tuesdays, Thursdays and Fridays and 8am- 12:35pm on Wednesdays and Saturdays. For Winter term (Time 2), the schedule was changed to 8:25am-5:35pm on Mondays, Tuesdays, Thursdays, and Fridays and 8:25am to 12:35pm on Wednesdays and Saturdays. Boarding students completed surveys at the end of Fall term (Time 1), and at the end of Winter term (Time 2). One of the questions asked students whether they had gotten at least 8 hours of sleep each night, or less than 8 hours of sleep each night, during the term. Additional questions asked of the students included: • I napped at least sometimes on school days this term. • I arrived late to class at least once in the past two weeks. • I struggled to stay awake and/or fell asleep in class at least once in the past two weeks. • I was too tired to do schoolwork somewhat or much of the time this term. % of students agreeing 100 90 80 70 60 50 40 30 20 10 0 Napped Late to Class H Fell Asleep Too Tired How many dependent variables are represented in this chart?
