Does ingesting honey, olive oil, or nothing improve a persons singing?

# data[].attributes.body
We found 200 men and women in the choral program at Berkeley College.

# data[].attributes.body
The selection method we used was assigning random numbers to singers from the Berkeley Choral Program. They were then picked at random by a random number generator and sectioned off into three groups based on the numbers chosen.

# data[].attributes.body
200 men and women in Berkeley's Choral program were either given Olive Oil, Honey, or nothing. They were told to take it every day for a month.

# data[].attributes.body
The explanatory variable was the type of substance each group was assigned whether if it’s honey, olive oil, or doing absolutely nothing.

# data[].attributes.body
When the month is over, the subjects were entered in a vocal competition.

# data[].attributes.body
What might impact our study would be the skill level of the singers before the study and what else the singers ingest daily. Randomization will be based on numbers of which the singers were separated by.

# data[].attributes.body
The control group in our study would be the subjects taking nothing everyday.

# data[].attributes.body
We can’t do a blind/double blind experiment because the singers will know what they are taking before performing.

# data[].attributes.body
The subjects could be matched by vocal parts. They would be divided by Soprano, Alto, Tenor, and Bass. This would be beneficial, because each part uses a different register to sing in i.e. chest, head, and mixed voice.

# data[].attributes.body
Our sample size was 200 men and women enrolled in the Berkeley Choral Program. The margin of error is 7.07 which predicts how well the singers will do with the improvement. This is good, because we will know that the improvement will be reliable.

This study could be replicated by using 200 other choral members. This would show the validity of the study

# data[].attributes.body
There was 60% improvement in choral singing with olive oil, 35% with honey, and only 5% had improvement by doing nothing.

# data[].attributes.body
The study was statistically significant. There was a 60% improvement with Olive Oil, 35% with Honey, and 5% when nothing was used. This shows that the substances were efficient in improving vocal performance.

# data[].attributes.body
There was $400 put into the experiment. This money went to all the honey and olive oil for the singers, and paper copies of the instructions for each group. Our salary was $800 to leave room for mistakes or any other conflicts.

# data[].attributes.body
Singers are swearing by olive oil, and now it has been proven that there is improvement in vocal performance. There has been an increase in Olive Oil sales for vocal improvement.
