whats the mean absolute deviation of
134, 138, 150, 155, 158, 165
To calculate the mean absolute deviation, follow these steps:
1. Find the mean of the data set:
Mean = (134 + 138 + 150 + 155 + 158 + 165) / 6
Mean = 139
2. Find the absolute deviations for each number in the data set:
|134 - 139| = 5
|138 - 139| = 1
|150 - 139| = 11
|155 - 139| = 16
|158 - 139| = 19
|165 - 139| = 26
3. Find the mean of the absolute deviations:
Mean absolute deviation = (5 + 1 + 11 + 16 + 19 + 26) / 6
Mean absolute deviation = 12.83
Therefore, the mean absolute deviation of the data set {134, 138, 150, 155, 158, 165} is 12.83.
