Q. In the data set below, what is the mean absolute deviation?\newline7,1,1,1,2,2,77, 1, 1, 1, 2, 2, 7\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 7,1,1,1,2,2,77, 1, 1, 1, 2, 2, 7.\newlineSum of data points: 7+1+1+1+2+2+7=217 + 1 + 1 + 1 + 2 + 2 + 7 = 21.\newlineNumber of data points: 77.\newlineMean = 217=3\frac{21}{7} = 3.
  2. Find Deviations: Find the absolute deviations from the mean for each data point.\newlineAbsolute deviation for 77 = 73=4|7 - 3| = 4.\newlineAbsolute deviation for 11 = 13=2|1 - 3| = 2.\newlineRepeat for all data points.\newlineAbsolute deviations: 4,2,2,2,1,1,44, 2, 2, 2, 1, 1, 4.
  3. Calculate Mean Deviations: Calculate the mean of the absolute deviations.\newlineSum of absolute deviations: 4+2+2+2+1+1+4=164 + 2 + 2 + 2 + 1 + 1 + 4 = 16.\newlineMean absolute deviation = 1672.2857\frac{16}{7} \approx 2.2857.
  4. Round Mean Deviation: Round the mean absolute deviation to the nearest tenth. 2.28572.2857 rounded to the nearest tenth is 2.32.3.
