- Abstract: The activity involves a set of data dealing with the percentage difference between measure calories and labeled calories of particular items, in two categories, per item and per gram. Students are asked to make stem-and-leaf plots, dotplots, and histograms of the two variables. The students are then asked to describe the distributions of the two variables: “per gram” and “per item” and compare the resulting distributions. The students are asked to use the appropriate descriptive statistics to describe the respective distributions.
