"Quality of sleep, as assessed by the Groniger Sleep Quality Questionnaire, did not show a significant relationship with academic performance. However, quantity of sleep was significantly related." (18). This information could be used to guide and narrow our study. More emphasis could be put on quantity (ie. number of hours of sleep per night) over the quality of sleep (ie. waking up in the middle of the night, frequency of waking up during sleep). We could apply the results that sleep quality is not a significant factor to GPA by focusing on the importance of rest and relaxation before (preparing for sleep) or after (pleasant and sufficient wake up time), which would technically count toward quantity of sleep.
