Chapter 1: Overview and Descriptive Statistics76. The measures that are sensitive to outliers are: the mean and the midrange. The mean issensitive because all values are used in computing it. The midrange is sensitive because ituses only the most extreme values in its computation.The median, the trimmed mean, and the midhinge are not sensitive to outliers.The median is the most resistant to outliers because it uses only the middle value (or values)in its computation.The trimmed mean is somewhat resistant to outliers. The larger the trimming percentage, themore resistant the trimmed mean becomes.The midhinge, which uses the quartiles, is reasonably resistant to outliers because bothquartiles are resistant to outliers.77.a.0 23555667778881 00001355552 002573 00334 00575 0446 stem: ones7 05 leaf: tenths8 89 010 3HI 22.0 24.541
