Sierra Mist vs Sprite Blind Test Dominick Hernandez Professor Duverger MKTG 441 11/20/2020

Hernandez2 Experimental Hypothesis Before I go into detail for the A/B testing sample, the reason behind this test is to see how a particular preference between two soft drinks influences a generation to choose that specific drink over another. I have decided to conduct a blind testing experiment sample with ten people blind taste testing with two soda brands that are Sierra Mist and Sprite. We will be testing the hypothesis based on “Gen-Z prefer sierra mist with natural ingredients compared to sprite that doesn’t contain natural flavors.” So before experimenting, I had to set up a place and time to have ten people within Gen-z come to the blind taste testing. I experimented with my house on Sunday, November 22, 2020, with 10 Towson University students within the proposed gen-z demographic. I made sure that the surroundings were minimal so they wouldn’t be distracted by unwanted noise. Setting up the Experiment/Procedure Before my participants arrived, I decided to set up at least two rooms to conduct the experiment where I would be in room number 1 for one period of time then I would change to room number 2 after the experiment conducted in room number 1 was completed. Then I gather my necessary supplies to conduct the experiment, which would be Sprite and Sierra mist at the same cold temperature, two red solo cups to pour the two beverages in. Finally, a copy of the survey I created contains one question and multiple options for answers and a pencil to record their responses. The survey question I made for this experiment was stated as “I prefer the taste of this particular beverage” with strongly agree, agree, somewhat agree, neither agree nor disagree, somewhat disagree, disagree, or strongly agree. I labeled both of the red solo cups A and B with a black marker. I poured Sierra mist in cup A and Sprite in cup B both without showing or providing any indication of what brand of soda they would be tasting.

Hernandez3 When my participants arrived, I explained how this experiment would be conducted separately so I separated all ten participants into two groups in two separate room, 5in each, to perform this blind taste-testing experiment. At last, the experiment began; when our first group of 5 participants tasted cup A which contained sierra mist, they would be required to complete a survey question before tasting cup B, which contained sprite. After tasting cup B, they would have to answer another survey question. It also applied to our second group of 5 people where they would in this case cup B first then they would answer a survey question before tasting cup A and answering the survey question thereafter. Results After conducting the results of the blind tasting experiment, I can conclude that our hypothesis of “Gen-z prefer sierra mist compared to sprite” was successful and proven valid by conducted survey questions that was provided by the twelve participants. By using a Top 2 box method, we were able to summarize the results of the survey question by focusing on the responses provided by the Strongly Agree and Agree results from the ten participants that were involved with this experiment. After calculating the results from the survey, I can conclude that the final results are that 80% Strongly agree/agree that preferred Cup A and 30% Strongly agree/agree with Cup B which in terms of the lift or difference between them would be 50%.

Conclusion •

Participants preferred Pepsi 90% of the time versus Coke 20% of the time.

•

The Lift or difference (70%) was statistically significant at a 95% confidence level given a margin of error of 31%.

Lift = 70%
