Our study was published in a journal called Medical World News to further back up that 8 hours is the right amount of sleep teenagers should be getting, any less or any more and they don’t perform at their best. Parents are now making sure their teenagers are going to bed at the right time to make sure they are at their full potential.

# data[].attributes.body
We randomized all 200 people and the randomized difference was 13 points. This in very significant as the 8 hours group was the only group who scored a 85 or higher everytime and consistently scored higher than the other treatment groups.

In the study we matched people by their gender, age, and IQ. There were 4 people in each group and each one of the 4 was randomly assigned a different treatment. This will help us compare accurate results in the end.

At the end of the study the average score for the people who slept for 0 hours was 22, the average for 4 hours of sleep was 49.6, the average for 8 hours of sleep was 92.6, and the average for 12 hours of sleep was 79.6. The highest performing group was the 8 hours group by an average of 13 points from the next highest performing group.

To replicate this study we will need 200 more students from a different school (O’Connor) to confirm our results are significant and correct. We will use the same selection method on math students.

With a sample size of 200 our margin of error is 7.07%. The lower margin of error is good and means the results should be a good representation of the population.

We had the school give us a list of all the students ID numbers and then used a random number generator to select 50 students from each grade level for each treatment group. Potential lurking variables are GPA and how hard each person sleeps.

We are not able to blind our subjects because the people getting no sleep will be aware of how much they slept. Their is also the possibility of students talking to each other before the test on how they are feeling or on how much sleep they got. Their is no double blind because the person incharge of waking up the subject will need to know what time to wake them up in order for the experiment to be successful.

Our control group is the 50 people who will be sleeping 8 hours since that is the recommended amount of sleep teenagers are supposed to get. We do not have a placebo as people know how long they will have slept.

Our experimental units were found by randomly choosing 50 math students from each grade level (freshman, sophomore, junior, and senior) by their student ID number and asking them if they would like to be a part of a sleep study.

We selected 200 men and women who were all students at Boulder Creek to be randomly selected to sleep and complete a logic test, their only commitment was a time based sleep session and a one hour test after.

# data[].attributes.body
The response variable is their scores on the logic test out of 100

# data[].attributes.body
Our explatory variable is the amount of sleep each person received.

# data[].attributes.body
50 subject are randomly selected to not sleep, 50 different subjects are randomly selected to sleep for 4 hours, 50 different subjects are randomly selected to sleep for 8 hours, and 50 more different subjects are randomly selected to sleep for 12 hours.

How does the amount of sleep affect how someone does on a logic test?
