A researcher is investigating different types of customers for a sporting goods store. In a survey, respondents are asked to use their exercise tracker devices (Fitbit, Altra, iWatch, etc.) to indicate how much they exercised last week using categories of “Less than 1 hour,” “Between 1 and 2 hours,” “Between 2 and 3 hours,” and so on. These respondents have also rated the performance of the sporting goods store across 12 different characteristics, such as good value for the price, convenience of location, helpfulness of the sales clerks, and so on. The researcher used a 7-point rating scale for these 12 characteristics where 1 = Poor performance to 7 = Excellent performance. How can the researcher investigate differences in the ratings based on the amount of exercise reported by the respondents?
