Nature sounds ended up being the most beneficial treatment for better sleep. Nature sounds had the highest average sleep of 8. Desired music was the least beneficial, seeing as the average was 4.6. Participants from this experiment decided to start listening to nature sounds as they fell asleep from then on. It is not proven as fact, but an idea that nature sounds improve wellness of sleep.

Of all the 21 randomly selected and grouped experimental units, there was a 2 number difference in the average sleep due to treatments. This 2 number difference is not significantly significant, although it is still evident which treatment which was most beneficial.

At the end of the 3 week long study, the average wellness of sleep a participant experienced with no sound was about a 6.3 on a 10 point scale. Nature sounds had an average of 8 on a 10 point scale. Desired music had an average of 4.6 on a 10 point scale. After this experiment was repeated, the results had not moved up or down too dramatically.

With a sample size of 21, our margin of error is 21.8%. Our higher margin of error gives us more of a reason to use repetition. Otherwise our results may not be as well representative of the population.

Our control group is the 7 participants who will be sleeping with no sound. In our repetition, we will randomize another 7 participants who will again sleep with no sound. This will eliminate some lurking variables.

We will replicate this study three other times, each experiment with a new group of 21 individuals. This will confirm our results to be valid and possibly significant. All the names in our family would be the sampling frame of which is randomized.

# data[].attributes.body
To choose our experimental units, we gathered names of all our family members excluding those who were conducting the experiment. All names were thrown into a random generator which selected 21 of them.

A total of 21 randomly selected family members were grouped into blocks of 7. Their assignment to the groups were randomized. Ax different treatment is held out within each group, so that all three treatments are performed once. Once this experiment is complete, the treatments are then compared. This design helps us determine the blocking variables that have an impact on the result, and we feel more confident weren’t due to those blocking variables not being blocked.

Sleep is a difficult concept to measure. The wellness of one’s sleep could be defined by not just outside noises, but also their breathing capability, possible sleep insomnia, or age of the experimental unit. The only randomization performed was the selection of the experimental units in the family and which treatment they will be given. Another lurking variable could be that putting each and every family member into the pile of options could be difficult. Some distant family members may not be accounted for, or some that are selected might choose not to be a part of the experiment.

We could not blind our subjects because they would be aware of the music they were falling asleep to, as well as what they woke up to it. This was neither blind nor double blind. Those who gave the treatments were aware of what they were assigning and putting on for their subject.

The no sound treatment was performed as a control group, to justify the liability of the other treatments.

Wellness of sleep in result to the sound/music played, rated by how deeply rested and relaxed the subject felt after the experimental sleep was over.

# data[].attributes.body
Type of sound that plays while the experimental unit is sleeping.

# data[].attributes.body
Seven randomly selected family members were assigned to sleeping with no sound, seven were selected to sleep with nature sounds, and seven were selected to sleep to their desired music. Each experiment was performed for eight hours during the night, with the experimental unit being alone in their room.

21 ramdomly selected family members (of any age) of the one performing this experiment.
