Huron Lakes Candies (HLC) has developed a new candy bar called Java Cup that is a milk chocolate cup with a coffee-cream center. In order to assess the market potential of Java Cup, HLC has developed a taste test and follow-up survey. Respondents were asked to taste Java Cup and then rate Java Cup’s taste, texture, creaminess of filling, sweetness, and depth of the chocolate flavor of the cup on a 100-point scale. The taste test and survey were administered to 217 randomly selected adult consumers. Data collected from each respondent are provided in the file JavaCup.
