Researchers collected data on 76 brands of cereal at a local supermarket. For each brand, the sugar content (grams per serving) and the shelf in the store on which the cereal was located ( \( 1= \) bottom, \( 2= \) middle, \( 3= \) top) were recorded. A dotplot of the data is shown here. Is the variability in sugar content of the cereals similar or different for the three shelves? The variability in distributions of sugar content is similar for the three shelves, as they all vary from about 0 grams per serving to about 15 grams per serving. The variability in the distributions of sugar content is different for the three shelves because there are far more cereals on the top shelf than on the other two shelves. The variability in the distributions of sugar content is different for the three shelves because their medians are different. The variability in the distributions of sugar content is similar for the three shelves because the minimums for all three shelves are exactly the same. The variability in the distributions of sugar content is similar for the three shelves because all three distributions are skewed. Researchers collected data on 76 brands of cereal at a local supermarket. For each brand, the sugar content (grams per serving) and the shelf in the store on which the cereal was located ( \( 1= \) bottom, \( 2= \) middle, \( 3= \) top) were recorded. A dotplot of the data is shown here. Do the data suggest the critics claim, that supermarkets tend to put sugary cereals where kids can see them? (Note that Shelf 2 is at about eye level for kids in most supermarkets.) Yes! The maximum of the second shelf is as high as it is for any of the other two shelves, indicating that the supermarkets tend to put sugary cereals where kids can see them on the second shelf. No, because the variability in all three distributions is about the same. Yes! The distribution of sugar content for shelf 2 , which is right at eye level for most kids, has the largest center indicating that supermarkets tend to put sugary kids' cereals where the kids are most likely to see them. No, because all three distributions are skewed. Yes! Only one box on the second shelf has 0 grams per serving while there are three such boxes on each of the first and third shelves.
