A demographic survey asked about their GPA and the courses they dropped, withdrew from, or failed to complete. This was done to judge the student’s previous academic levels. Next, they took what is called the GDI to determine the student’s levels of depression. Students who showed abnormally high levels of depression were removed from the study to be further analyzed. The students remaining had scores of average or below average levels of depression. The final test was the PSQI, which is a self-report survey to determine the subjects sleep patterns. Using these self-report surveys the conductors of the experiment were able to determine that there is a relationship between quality of sleep and academic performance. Significance

Previous studies used smaller groups and had not accounted for depression as a factor in poor academic performance. This study also found that the quality of sleep many students experience...
