Q. In the data set below, what is the mean absolute deviation?\newline1,3,3,8,1,21, 3, 3, 8, 1, 2\newlineIf the answer is a decimal, round it to the nearest tenth.\newlinemean absolute deviation (MAD): __\_\_
  1. Calculate Mean: Calculate the mean of the data set 1,3,3,8,1,21, 3, 3, 8, 1, 2.\newlineSum of data points: 1+3+3+8+1+2=181 + 3 + 3 + 8 + 1 + 2 = 18.\newlineNumber of data points: 66.\newlineMean = 186=3\frac{18}{6} = 3.
  2. Calculate Absolute Deviations: Calculate the absolute deviations from the mean for each data point.\newlineAbsolute deviation for 11 = 13=2|1 - 3| = 2.\newlineAbsolute deviation for 33 = 33=0|3 - 3| = 0.\newlineAbsolute deviation for 33 = 33=0|3 - 3| = 0.\newlineAbsolute deviation for 88 = 83=5|8 - 3| = 5.\newlineAbsolute deviation for 11 = 13=2|1 - 3| = 2.\newlineAbsolute deviation for 13=2|1 - 3| = 200 = 13=2|1 - 3| = 211.
  3. Calculate Mean of Absolute Deviations: Calculate the mean of the absolute deviations.\newlineSum of absolute deviations: 2+0+0+5+2+1=102 + 0 + 0 + 5 + 2 + 1 = 10.\newlineMean absolute deviation = 106=1.666\frac{10}{6} = 1.666\ldots\newlineRounded to the nearest tenth = 1.71.7.
