Does involvement in sports effect how much sleep students get?


Students who spend nine hours or more working out (are athletic) will receive fewer hours of sleep than students who spend less than nine hours working out (not athletic).

The amount of time a student sleeps is not affected by whether or not they are involved in sports. When interviewing both athletic and non-athletic students (students were considered athletic if they participated in sports for over nine hours in a week) we found that regardless of the amount of hours spent on athletics, everyone said they got between six and eight hours of sleep. When comparing both sets of data (non-athletic and athletic) we calculated a P Value of about 0.06. With this information, we were able to determine that the data sets were not significantly different because the P Value is above 0.05. Through research, it became apparent that students in general do not get much sleep during the school year due to how early school starts. Studies have shown that teenagers should get 8.5 to 9.5 hours of sleep a night. However, most teenagers have to stay up until 11 pm or later in order to finish homework. Then they have to wake up at 7 am, or earlier, in order to get to school on time. They should be sleeping in until 8 am at least, which is the typically before school starts. Thus, students would most likely be better off if school started at a later time and would get more sleep, regardless if they participate in sports or not.


The average hours of sleep a student gets per week is not affected by their involvement in sports. We discovered that regardless of being athletic (by our standards), students typically received between six and eight hours of sleep. This is because school starts at such an early time and teenagers usually go to bed after 11 pm, decreasing the hours of sleep they receive.

Sources of Inaccuracies/Errors

Perhaps some of the people interviewed who were considered non-athletic were involved in other extracurricular activities that decreased the hours of sleep they typically received.

Another error that could have occurred during this experiment is the interviewees might have incorrectly estimated their sleep time and/or time spent working out.

When collecting our data, we did not collect data from an equal amount of athletic and non-athletic students.
