How do different noises effect someone’s quality of sleep?

# data[].attributes.body
Our control group would be the subjects who are participating in the study and who are sleeping without noise. No noise is the control

# data[].attributes.body
We chose 97 subjects from the age of 18-30 who were recently shopping for sleeping supplies.

# data[].attributes.body
We found our subjects by going to local stores which provided sleep supplies. We then asked the individuals how many hours of sleep they got per night. If it was less than 5 we then asked if they’d like to participate in our study.

# data[].attributes.body
Our explanatory variable was each treatment the subjects received including no noise.

# data[].attributes.body
After all the subjects have received all treatments, we will then compare the quality of sleep through each treatment. This is done through a decvice connected to their brain to track the brainwaves, verifying they’re quality of sleep

# data[].attributes.body
We numbered our subjects 1-97 and then used a random number generator to assign them to the certain groups. Some lurking variables could be their history with sleep, how comfortable they are sleeping outside their home and possibly how the sleep study setting changes the quality of their sleep

# data[].attributes.body
We performed a cross over study where all of our subjects were exposed to each treatment. Our treatments include sleeping with no noise, a white noise machine, TV on, and ocean sounds. This is done so that every subject experiences every treatment and we can get the best results possible.

# data[].attributes.body
Our sample size could’ve been bigger at 97. With this we produced a margin of error of 10.15. This isn’t exactly low enough, but it is a good start in order to start the replication process

# data[].attributes.body
We will replicate this experiment by going to a college and setting up an add for the study. That way will will have more participants and it will be more specific

# data[].attributes.body
We will not be able to blind our subjects because they will obviously know what treatment they are receiving based on their hearing.

# data[].attributes.body
Prior to the experiment we matched those who were close and the same age, and had similar sleeping patterns. We the. Assigned one the control, and one with the treatments. This will help to compare results later in the study

# data[].attributes.body
At the end of the study we found that ocean noises helped people sleep the most, 8 being the most common hours of sleep gained. However the rest of the results were very random

# data[].attributes.body
Our study will not be published because of the poor results. We will replicate with more subjects with stricter conditions and try again.

# data[].attributes.body
There is none because the results are skewed and random. This isn’t because possibly we couldn’t have enough subjects for accuracy. There are also factors of lurking variable that could have changed the data.
