This project was replicated using 200 different students, in order to have an even smaller margin of error. The results of the replicated experiment also showed that when less technology is used before bed, a higher quality sleep is received. After finding these results many parents and schools encourage students to lessen technology use before sleeping in order to feel more rested and

Although this is an experimental study (not an observational study), it should be relatively cheap to run this project. The experimental units (the students) already have access to technology at home through a computer, phone, or laptop. Overall, it is more time consuming then expensive.

In order to reduce bias and lurking variables, the students will be generated randomly and will take the treatments in a crossover design. Through randomly assigning students and treatments, there is a wide variety of experimental units and their treatments.

How does technology use affect the quality of sleep in teenagers?

# data[].attributes.body
The experimental units will be 100 Boulder Creek students, they will be selected using a numbered roster of all the students. 25 students will be randomly generated from each grade to participate (make sure students agree to be part of the experiment).

# data[].attributes.body
There are four different treatments which are different amounts of technology use before sleep. Students will be exposed to technology at different times before bed: No technology at all, technology 3 hours before bed, technology 1 hour before bed, and Technology right before bed.

# data[].attributes.body
The explanatory variable will be when/how long technology is used before sleeping (four different treatments).

# data[].attributes.body
The response variable will be the quality of sleep each subject experiences, it will be measured using a 1-10 scale taking into account duration and immersiveness.

# data[].attributes.body
There will be one treatment where technology isn’t used at all before sleep, this treatment will be examined as a control within the experiment.

There is no blind or double blind element in the experiment as both the testers and subjects are aware of the treatments being used each time.

# data[].attributes.body
This experiment will be executed with a crossover design as each experimental unit will receive all four treatments randomly on different night (one per night).

This study uses 100 students, so the margin of error is around 10%. This is a somewhat low margin of error so my results will likely be representative of the population

This study could be replicated by generating 100 more students to partake in the experiment. If it was replicated, other amounts of time might be used in the treatments to add more confidence to the results.

# data[].attributes.body
The majority of students reported a higher quality sleep when not using technology right before bed. The students who used technology right before bed reported a lower quality sleep. The difference in sleep quality averages were drastic enough that this study is statistically significant
