They were then picked at random by a random number generator and sectioned off into three groups based on the numbers chosen. ]]> 2017-11-07 16:01:33 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204422040 caker902 https://padlet.com/cmbra257/8op01s33apw8/wish/204424408 The explanatory variable was the type of substance each group was assigned whether if it’s honey, olive oil, or doing absolutely nothing.]]> 2017-11-07 16:05:06 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204424408 caker902 https://padlet.com/cmbra257/8op01s33apw8/wish/204426460 What might impact our study would be the skill level of the singers before the study and what else the singers ingest daily.

They were told to take it every day for a month. ]]> 2017-11-07 16:08:23 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204426863 caker902 https://padlet.com/cmbra257/8op01s33apw8/wish/204428225 We can’t do a blind/double blind experiment because the singers will know what they are taking before performing.]]> 2017-11-07 16:10:30 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204428225 cmbra257 https://padlet.com/cmbra257/8op01s33apw8/wish/204428419 When the month is over, the subjects were entered in a vocal competition. ]]> 2017-11-07 16:10:46 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204428419 cmbra257 https://padlet.com/cmbra257/8op01s33apw8/wish/204429722 The control group in our study would be the subjects taking nothing everyday. ]]> 2017-11-07 16:12:50 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204429722 caker902 https://padlet.com/cmbra257/8op01s33apw8/wish/204430263 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.]]> 2017-11-07 16:13:44 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204430263 cmbra257 https://padlet.com/cmbra257/8op01s33apw8/wish/204430778 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.]]> 2017-11-07 16:14:35 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204430778 cmbra257 https://padlet.com/cmbra257/8op01s33apw8/wish/204432609 This study could be replicated by using 200 other choral members.

There was a 60% improvement with Olive Oil, 35% with Honey, and 5% when nothing was used.

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. ]]> 2017-11-07 16:20:18 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204434798 caker902 https://padlet.com/cmbra257/8op01s33apw8/wish/204440077 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. ]]> 2017-11-07 16:27:41 UTC https://padlet.com/cmbra257/8op01s33apw8/wish/204440077
