Suppose that the makers of a new candy bar want to determine whether an international market of teenagers would be interested in their product. So, in a period of two months, the firm conducts interviews and taste tests in a number of supermarkets in U. S. cities, asking shoppers for their opinion of the new candy. Which of the following statements best describes the results of such a research study? A. The study might be internally valid, but it is definitely not externally valid.
B. The study might be externally valid, but it is definitely not internally valid.
C. This research design is a good example of "predictive technology."
D. If the new candy contained bits of Oreos, you could say that the firm was collecting "cookies."
E. Because the research was conducted in supermarkets that sell candy, the participant sample is likely to be considered representative.
