Table 8 Discussion Students who get better grades tend to go to bed earlier on school nights and, consequently, get more sleep on school nights.
Most students get over an hour and a half more sleep on weekend nights as compared to school nights.
The Minnesota results are remarkably similar to the Rhode Island study results in this respect. This may mean that Minnesota schools suffer more from grade inflation. Again, these findings are similar to the Rhode Island findings. The older students get, the later they go to bed, and consequently, the less sleep they get. The Minnesota 17-19 year olds are averaging 6 hours and 43 minutes of sleep on a school night.
