1. Coke vs. Pepsi
The Classic Fight

2. Procedure
Question: Can people taste the difference between Coke and Pepsi?
Steps:
We sampled 53 people that we knew with a variety of ages and a well-balanced ratio of males to females.
Each of us had a table to record gender, age, and whether or not the subject guessed correctly.
We labeled 2 cups: Cup “A” and Cup “B.”
Cup “A” was Coke and Cup “B” was Pepsi.
We told the subject that one cup had Coke in it and the other cup had Pepsi in it.
The subject tasted the soda in Cup “A” and the soda in Cup “B.”
The subject attempted to correctly identify the soda in each cup.
We recorded the information and results in the table.
We created graphs to display the information.
