Name: Dr. Pepper Taste Test

 

Abstract: This experiment was designed to see if participants could distinguish the difference between diet and regular Dr. Pepper.  Two hundred and seventy-six participants were asked to taste diet and regular Dr. Pepper.  They were either given diet, regular, or no soda before they took the taste test (ie, “pre-soda”).  Some participants were told what kind of pre-soda they were given while others were not to see if it impacted their ability to tell the difference between diet and regular Dr. Pepper.

 

Variables (column):

  1. Gender (0=Female, 1=Male)
  2. PreSoda (what soda was given to the participant before the regular vs diet test, 1=None, 2=Diet Dr. Pepper, 3=Regular Dr. Pepper)
  3. ToldWhatPreSoda (whether the participant was told what type of Dr. Pepper he was given before the regular vs diet test, 1=Had No Soda Before the Test, 2=Was Not Told, 3=Was Told)
  4. CorrectResponse (Could distinguish between regular and diet Dr. Pepper, 0=No, 1=Yes)
