The case study was:
Assume you are reviewing the research data from a cola taste test. Each participant in the experiment first tasted two ounces of Coca- Cola; then two ounces of Pepsi-Cola; and then two ounces of Sam's Choice Cola. A rating of each cola's flavor was made after each taste using a 10-point scale.
1. Assess whether using a 10-point scale was appropriate for this cola taste test research study.
2. Evaluate possible problems associated with this experimental design.
3. Develop an alternative design for this research study.
