Carrelation Between Sleep and Grades

Correlation between Sleep and Grades Hours of Sleep (h) | 5 | 5 | 6 | 6 | 6 | 7 | 7 | 7 | 7 | 8 | Average of Term (%) | 68 | 73 | 80 | 81 | 82 | 83 | 84 | 85 | 87 | 80 |

Correlation is a statistical measurement of the relationship between two variables. Through many years, people have been studying the correlation between sleep length and average grades, and to what I have found, I believe there is. Looking at my research I have seen a direct correlation that the more sleep a student gets, the higher their average will be. Pamela Thacher, associate professor of psychology at St. Lawrence University says that side effects of sleep deprivation include delayed reactions and tendencies to make mistakes, also a decreased ability to concentrate.
Adolescents need more than 9 hours of sleep each night. Many kids may not get these hours of sleep due to working, eating, television, internet, homework, or sleeping patterns. When I asked why they were getting so little sleep, many answers were, I was on the computer, or I was watching television. Very few answered “I was doing homework”. Sleep is one of the most important things to keep the body and mind functioning correctly. A 1998 study by psychologists Amy Wolfson and Mary Carskadon that students who earned C's, D's and F's were getting about 25 minutes less sleep per night than students who earned A's and B's.
All students have activities, homework, and other things that must be done, and we tend to forget the importance of sleep. The lack of sleep can also be linked back to time management, which many of us high school students tend to lack and procrastination. The lack of prioritizing and organization causes us to forget about things and causes us to stay up late to complete the assignment.
Studies have shown that those who study at night and get a good night sleep, about 8 hours, remember more and get better results on the exam. The correlation is .85 which is strong, so I can conclude that the number of hours of sleep truly impacts how well someone can do in school. But as technology advances, people find more excuses to stay up late, no realizing the consequences it has on their schooling. In 10 years, it won’t matter how much time you spent on Facebook, or watching television, it matters how good your marks are so that you can have the future that you want. http://www.ehow.com/facts_6370658_effects-sleep-grade-point-average.html#ixzz1IZtCR3B4 http://www.sciencedaily.com/releases/2007/11/071130162518.htm http://www.educationworld.com/a_curr/curr340.shtml
