The cola wars


  1. Identify a member of your group who claims to be able to tell the difference between Pepsi and Coke. (Coke Classic, that is; accept no substitutes!) Design and carry out an experiment to test whether this is true. Remember that one swallow doth not a summer make: Don't certify your taste-tester just on the basis of one experiment. Decide exactly what data you will collect and what you will do with the data before you start collecting it. Also, remember the story of clever Hans, and consider the benefits of a double-blind study. (We also have RC cola available; if you prefer, you may want to see if your taste-tester can distinguish RC from Coke or Pepsi.)

  2. Apparently, the formula for Coke was changed because taste tests showed that something like of Americans prefer the taste of ``new'' Coke to that of Coke Classic. Discuss the wisdom of this.

  3. Why is there no such thing as Diet Coke Classic?
