What Gender Can Tell The Diff erence Between Coke Products Better?
Tessa Nelson9th GradeBellwood Antis High School
Sense of TasteGirls & boys have same # of taste buds but girls have a higher sensitivity level
Boys need an average of 10% more sourness and 20% more sweetness.
The Sweetness is what I’m testing.
Girls do have a better sense of taste then boys.
Six Dixie cups, filled with 40 milliliters of the Coke products, and one with water
The blindfolded subjects come in and drink the soda one by one, drinking the water after each.
They were told what choices they could chose from.
They told us their answers after each drink.

Conclusion
My data does not support my hypothesis. Therefore I reject my hypothesis; Girls
can not tell the difference between coke products better than boys.
If I were to do this
