718 Chapter 15-Statistics: 11. Determine the medians and interquartile ranges for the hypothetical test scores shown in each. of the dot plots of Figure 15.39. Each dot plot has 28 pieces of data. Use the medians and in- terquartile ranges to discuss and compare the re- sults on the two tests. 012345678910 od - C2 0000002 012345678910 Figure 15.39 Dot plots showing hypothetical test results. TABLE 15.6 Fifth-grader names 12. a. Make box plots for the dot plots in Figure 15.39 b. Suppose you only have the box plot from part (a) and you don't have the dot plots in Figure 15.39. Use the box plots to discuss how the data sets compare. 13. A fifth-grade class is wondering if girls' names tend to be longer than boys' names. Table 15.6 shows the names of all the fifth-grade girls and boys at the school. a. Display the lengths of the fifth-grade girls' and boys' names in dot plots. Compare the dot plots. b. Write and answer at least four questions about your dot plots from part (a), includ- ing at least one question at each of the three graph-reading levels discussed in Section 15.2 (Read the data, Read between the data, and Read beyond the data).
