Demonstrate CBC Using Only Basic Math

This survey will illustrate how Choice-Based Conjoint surveys work. It involves choosing food for dinner at a baseball game. You will take a quick 9-question CBC questionnaire, and then, using simple addition arithmetic, we will analyze your results and place the results into a "what-if" market simulator to see how your results stack up against others who have completed this survey.
