whats the mean absolute deviation of
134, 138, 150, 155, 158, 165
56
9.3
150
11.2
The mean absolute deviation is calculated by finding the average of the absolute differences between each data point and the mean of the data set.
First, find the mean of the data set:
(134 + 138 + 150 + 155 + 158 + 165) / 6 = 140
Next, find the absolute difference between each data point and the mean:
|134 - 140| = 6
|138 - 140| = 2
|150 - 140| = 10
|155 - 140| = 15
|158 - 140| = 18
|165 - 140| = 25
Now, find the average of these absolute differences:
(6 + 2 + 10 + 15 + 18 + 25) / 6 = 76 / 6 = 12.67
Therefore, the mean absolute deviation is 12.67. The closest answer provided is 11.2.
