How does sleep effect students test scores?

# data[].attributes.body
Once the groups are randomly split up into two groups, one of the 250 students will be given 8-10 hours of sleep before they are given a test. The other 250 students will be only given 4-6 hours of sleep before they are given a test.

# data[].attributes.body
We found 500 students, 250 students who have a gpa between 3.00-4.00, the other half have a gpa between 2.00-1.00. Than they re randomly selected and split in to two groups equaling 250.

# data[].attributes.body
Students who receive 8-10 hours of sleep will be considered the control group because it is reccomeneded to get at least 8-10 hours of sleep.

The explanatory variable is how much sleep each group was given.

After all 500 students take all five tests, their scores will be calculated by their group and averaged.

If students use substances that help them wake up and be more alert; like coffee, energy drink, or other substances could alter their performance on the test.

To alter this experiment as a blind experiment students will not know the time of the alarm until it rings. To create a double-blind experiment testers and students will not know which student gets what alarm.

To create a randomized block design students will be split up by their gpa percentage. To make sure that students who have a higher gpa are not skewing the test average in minimal sleep as well as students with low gaps but enough sleep.

To make sure our study is true we will have to replicate our experiment. Taking a new 500 students with all ranges of gpa and give them sufficient time to sleep and little sleep. This will make sure no lurking variables effected the data.

# data[].attributes.body
With our sample size of 500, our margin of error is 10.8. This is a somewhat high margin or error but that is not the biggest deal.

At the conclusion of our sleep study, we found out that no matter how smart a student is (gap wise) they need more than 8-10 hours to do well on a test. Students who did get 8-10 hours scored around the 80's, students who got 4-6 hours scored the 50's.

# data[].attributes.body
Our experiment was statistically significant because we found that the amount of sleep drastically alters test scores no matter the student's gpa.

Our results were used in many districts for lowering school starting times. And has helped kids around the United States sleep in longer to get better grades.
