Problem: Professor Foley conducted a cola taste test. Each participant in the experiment first tasted 2 ounces of Coca-Cola, then 2 ounces of Pepsi, and finally, 2 ounces of RC Cola. A rating of the cola's flavor was made after each taste. What are the potential problems with this experimental design and the procedures used? Revise the design and procedures to address these problems. You may wish to consider several alternatives and think about the advantages and disadvantages of each.
