| | congnitive skills |
| | Abstract | The purpose of this experiment was to determine if there is a correlation |
| | between a greater amount of sleep and better mental performance in |
| | cognitive skills, such as reading comprehension and logic, as well as |
| | memory. A random sample of 50 undergraduate students from University |
| | of Michigan was collected. Students were asked to complete a |
| | questionnaire involving a reading comprehension test, a logic test, and a |
| | memory test. The number of hours of sleep each student got was |
| | recorded as well. Data was presented in the form of bar graphs with the |
| | number of hours of sleep categorized as less than 7 hours, 7 to 9 hours, |
| | and greater than 9 hours. The experiment supported the hypothesis as |
| | subjects who slept for less than 7 hours had the lower scores than |
| | subjects who had 7 to 9 hours of sleep. Subjects with over 9 hours of |
| | sleep also had lower scores than those who slept 7 to 9 hours per night. |
| | However, one-way ANOVA (Analysis of Variance) suggested the need to |
| | repeat the experiment to better judge the role of sleep in performance in |
| | memory and coginitive skills. |
