Decrease in stress levels.

# data[].attributes.body
The significant decrease in heart rate and blood pressure while listening to classical music, signifies that music does affect stress levels depending on the genre of music.

# data[].attributes.body
Classical music had a average heart rate of 80bpm
Metal had an average of 120bpm
Rap had an average of 108bpm

The subjects worked a total of 100 hours during this experiment. Each subject volunteered/agreed to be a part of this experiment so  was necessary to pay the subjects. We did thank them and appreciate their time for being a part of this experiment. 100 hours is equal to 30 days.
30 days x $15= $450
100 subjects x $450= $45,000

The sample size is of 100 subjects, our margin of error is at 10%. This low margin of error is good and means that the results would be a good representation of the population.

For this experiment we will not be able to blind our subjects. Only because they will know if they are listening to music or not on a daily basis. The subjects will be assigned to listen to music or do you not listen to music for an hour in the car each day. There is also no double blind a part of this experiment, because our subj for this experiment we will not be able to blind our subjects. Only because they will know if they are listening to music or not on a daily basis. The subjects will be assigned to listen to music or do you not listen to music for an hour in the car each day. There is also no double blind a part of this experiment, because  amount of subjects we have is too small and we all know which subject is in which treatment group.

For this experiment, people were matched up by stress levels, gender, and age. Prior to the study and randomly picking subjects we had  randomly picked subjects to listen to music or do you not listen to music.  This matched pair design with this experiment will help us compare the results at the end.

Is listening to music an effective way to decrease stress?

# data[].attributes.body
We had rented cars for a total of 100 people. We numbered the subjects and used a random number table to select 100 for the treatment group. Potential lurking variables are stress levels, age, and gender.

# data[].attributes.body
We will replicate the study with 100 new subjects, to confirm the results are valid and significant.   Will run experiment like we did the first time and measure the stress levels at the end of this second trial.

# data[].attributes.body
Our control group is the 50 subjects who did not listen to music daily for an hour. We do not have a placebo, as that is not possible for this experiment.

At the end of the four weeks, we did a test on each subject by doing a blood sample. This is to sampl at the end of the four weeks, we did a test on each subject by doing a blood sample. This is to measure of the subjects stress levels.

# data[].attributes.body
The explanatory variable was whether or not the subjects listen to music daily. Depending on what the subject was assigned to, they either listen to music for an hour or didn’t listen to any music every day.

# data[].attributes.body
50 subjects were randomly assigned to listen to music and drive for at least a hour per day.  The other 50 subjects were to not listen to any music and drive for at least an hour per day.

Our experimental units were found by the local community. A News post was sent out to ask if these men and women wanted to be a part of this 4 week experiment.

# data[].attributes.body
We found a total of 50 women and 50 men who are licensed drivers to be a part of this commitment for 4 weeks.
