Question: Does the amount of computer activity a student does before going to bed affect the number of hours they sleep? Explanatory Variable: Hours on the computer Response Variable: Hours sleep

I will test 15 males, and 15 females. I will ask how many hours of computer activity they have each over a three night span and then see how many hours they have slept in that time.

I expect to see a negative correlation. As the number of hours on the computer increases there will be a decrease in the number of hours slept.

Data:

Number of hours slept = slope (number of hours on the computer) + intercept

My prediction that there will be a negative correlation was partially supported. The male data had a negative correlation but the females had a weak positive correlation. When the data was added together there was not a positive or negative correlation shown. Some lurking variables could be if males tend to play video games more than females, or if females tend to want to get more "beauty sleep". Also if could depend on what classes they may be taking. Depending on the class requirements, a computer may be needed or used by certain students.
