Coke or Pepsi

Filed under: All,Opinion |

I wanted to test how well Nichols Students could differentiate Pepsi from Coca-Cola based on taste. In elementary school, during a science fair, a fifth grader did a project on how well people could tell the difference between Pepsi and Coca-Cola. I loved soda and always imagined doing a project like this myself. I collected data in a two-day period, and I used a convenience sampling method. My population is the Nichols student body, my sample is thirty students, my parameter is the percent of people who were not able to differentiate which soda was which and matches it to the soda they said they preferred previously. For both sampling days, I had a station set up with Pepsi and Coca-Cola, Dixie cups, questionnaires, and pencils. I had students answer the questions, what is your gender, what grade are you in, do you prefer Pepsi or Coca-Cola, and, after having them taste both cup A and B, which cup do you like better. Cup A was always Pepsi, and Cup B was always Coca-Cola.

Out of thirty students, 60% (18/30) of the students chose Coca-Cola as the drink they prefer and 40% (12/30) of the students chose Pepsi. But, 56% (17/30) of students chose Cup A, and 44% (13/30) of students chose Cup B.

The graph on the left represents the number of students who correctly and incorrectly guessed which cup contained the drink that they preferred, Coca-Cola. Out of the 18 students who chose Coca-Cola as the drink that they prefer, 44% (8/18) students incorrectly guessed which cup matched Coca-Cola. The graph on the right represents the number of students who correctly and incorrectly guessed which cup contained the drink that they preferred, Pepsi. Out of the 12 students who chose Pepsi, 25% (3/12) of students incorrectly guessed which cup matched Pepsi.

These graphs suggest that people who choose Pepsi as their drink of choice are more able to differentiate Pepsi and Coca-Cola.
