13.7 STEM-AND-LEAF PLOTS The great thing about back-to-back stem-and-leaf plots: We can easily compare data! EXAMPLE: The ages of 2004 Olympic gymnastics teams. Make a back-to-back stem-and-leaf plot of the data. What can you generalize about the ages of the men and women in the 2004 Olympic gymnastics teams? Men were generally older than the women Women Men 43117

13.7 STEM-AND-LEAF PLOTS EXAMPLE: The ages of 2004 Olympic gymnastics teams. Make a back-to-back stem-and-leaf plot of the data. 1. What is the mean, median, mode and range for the men’s ages? Women Men 43117
