Average Sleep on Monday and Sunday

By: Thomas Du and Kovida Koneru

Question?

How much sleep does a student with 4 or more AP classes get on Sundays and Mondays on average?

Hypothesis

The average amount of sleep that a student with four or more AP classes gets on Sundays will be 8 hours and the average amount of sleep that a student with four or more AP classes gets on Mondays will be 6 hours.

Type of Investigation

This is a comparative investigation because the two days of the week, Monday and Sunday, will be compared to each other by the average amount of sleep.

Analysis

Does a student with 4 or more AP classses at CHS get on average 8 hours of sleep on Sundays and 6 hours of sleep on Mondays? According to the data, the hypothesis is incorrect, and the average amount of sleep on Sundays is only 7 hours, and about 6 and 1/2 hours on Mondays. There are several reasons why the amount of sleep from the results is inconsistent with the hypothesis, but the most discernable one may be the fact that teenagers have very active hormones that change the body's internal sleep clock, and causes them to stay up later than usual (National Sleep Foundation). Some students happen to take advantage of the lack of sleep by staying up working on homework, hence the AP classes, while others may stay up watching TV, or playing video games. According to other studies, the data that was collected from this experiment is consistent with other experiments conducted by Nationwide Childrens, where the amount of sleep recorded by the average teen is 7-7 and 1/4 hours of sleep (Nationwide Childrens). This makes way to believe that what affects sleep in teens is less task oriented, but more biologically responsible. However, depite the difference in national average amount of sleep for teens, and the amount of sleep that was recorded for students with 4 or more AP classes at CHS, the calculated P-value by T-test shows that the difference is insignificant, because the P value must be less than .05, and the calculated P-value was .054, which shows an insignificant difference between the amount of sleep on Mondays and Tuesdays.

Conclusion

The average amount of sleep that a student with 4 or more AP classes on Sundays is about 7 hours and about 6 hours on Mondays. According to the T-Test that was calculated, the P-Value was .054, which is .004 more than .05, and for there to be a significant difference, a p-value of .05 or lower is needed. Therefore, the hypothesis was incorrect, and the average amount of sleep that a student at CHS with 4 or more AP classes gets on Mondays and Sundays is insignificantly different.

Sources of Error

In this experiment, the error could have been that the people being experiments estimated the data. This could skew the results because the average amount of sleep could be miscalculated causing the data to be inaccurate. Another source of error can be that more people are likely to have more sleep on a Monday than any other weekday. This is because most people tend to finish their work over the weekend allowing them to have more sleep on Sunday night. Since this was a random sample, there could have also been the fact that some people have to deal with insomnia or other sleeping disorders. This could skew the data because the average of these hours could have been altered. Thus, this could cause inaccurate results. These factors are just a few out of many that has caused the experiment to have been skewed.
