A fitness lab has conducted an experiment in which 100 participants engage in a 30-minute period of high-intensity interval training (HIIT) and then are asked about their perceived level of exertion. They must select an answer from 1 to 4, where 1 = "did not feel challenged"; 2 = "broke a sweat but could have been pushed more;" 3 = "felt challenged but not overwhelmed;" and 4 = "extremely fatigued." In addition, each participant's body fat percentage is recorded. The following table displays a portion of the data from the experiment. Participant Body Fat Percentage Exertion Level 1 27 3 2 31 4 3 24 1 4 21 2 5 14 4 What is a good way to show how body fat percentage is related to exertion level? scatter chart depicting relationship between body fat percentage and exertion level sparklines on data unstacked so columns correspond to different exertion levels clustered column chart of body fat percentage with different colored columns for each exertion level side-by-side box and whisker plots of the distribution of body fat percentage for participants at each exertion level
