Eight friends are discussing their part-time jobs. They worked the following numbers of hours last week: [math]\, \, \, \, \, 8 \, \, \, 6 \, \, \, 8 \, \, \, 4 \, \, \, 8 \, \, \, 14 \, \, \, 10 \, \, \, 14[/math] Describe the data set, using appropriate measures of center and spread. Identify any outliers or other extreme values and describe their effects.

[*]Find the mean, [math]\bar{x}[/math]. [*]Choose appropriate measures of spread. [*]Find the range. [*]Calculate the mean absolute deviation, the variance, and the standard deviation for individual data values. [*]Find the mean absolute deviation (MAD), the variance, and the standard deviation for the data set. [*]Draw a box plot. [*]Draw a dot plot. [*]Use the plots to describe the data set. [/list]
