Song Lengths Side-by-side box-and-whisker plots can be used to compare two or more different data sets. Each box-and-whisker plot is drawn on the same number line to compare the data sets more easily. The song lengths (in seconds) from two different compact discs are given. Disc 1 177 200 210 220 240 Disc 2 200 224 275 288 390 150 175 200 225 250 275 300 325 350 375 400 10. Which box plot has a greater mean? How can you tell? 11. Which distribution is more likely to have outliers? Explain your reasoning. 12. Describe the shape of each distribution. Which is more likely to be skewed left? Why? 13. Which set of data has a smaller standard deviation? How do you know? Use the box and whisker plots to determine the following (a) the minimum entry. (d) the second quartile. (b) the maximum entry. (e) the third quartile. (c) the first quartile. 14. 15. 10 13 15 17 20 100 130 205 270 320 10 11 12 13 14 15 16 17 18 19 20 21 100 150 200 250 300
