Students from the 7-8 hours of sleep group reported a strong ability to focus and perform diligently. They had little to no change in GPA and reported a feeling of optimism. The second group reported little change to how they normally feel during school, as this was already the average amount of sleep they got regardless of the experiment. They had minor changes in grades, though they clarified it had little to do with feeling tired. The third group had a moderate decline in GPA throughout the week, and also reported feeling of crankiness, and trouble focusing in class. They also reported minor issues when it came to interacting with others. The final group reported majoe academic and social perfomance decline, as they found it extremely difficult to stay awake during classes, and had very little motivation to socialize.

I plan on repeating the experiment with younger grade levels, along with another random sample of seniors to gain more accurate results.

# data[].attributes.body
My sample size was 100 students, and the margin of error is .06%

I could have had people alternate the amount of hours, or i also could have had people do a before and after survey to gauge their mood from the begining of the week to the end.

I could have done matched paired designs, however I chose to sample random high school seniors. I could have had younger grades participate as well, but to me, that could have skewed results.

I made sure each group was evenly split up into 4 groups, and were kept unbiased.

My experiment didn't have any blinding factors, as each student was aware of the amount of sleep they were getting and consequently will be aware of the performance.

I suppose the control group could be the first group that gets the recommended amount of sleep.

I seperated the 100 students into 4 groups. I asked the first 25 students to ensure they got the recommended 7-8 hours of sleep every night for 7 days, and to report any fluctuation in grades, relationships, and general academic/ social performance. I asked the next 25 students to get 5-6 hours, the next to get 3-4, and the final group to get anywhere from 0-3.

I randomly selected students and asked if they would be willing to participate in a sleep study. I got 100 of them to agree.

I wanted to research the correlation between student's amount of sleep/ lack thereof and how well they performed in school.
