The mean of the dataset is (134+138+150+155+158+165)/6 = 145.
To find the mean absolute deviation, we first need to calculate the deviation of each data point from the mean:
|134-145| = 11
|138-145| = 7
|150-145| = 5
|155-145| = 10
|158-145| = 13
|165-145| = 20
Next, we find the average of these deviations:
(11+7+5+10+13+20)/6 = 11.0
Therefore, the mean absolute deviation of the dataset {134,138,150,155,158,165} is 11.0.
Determine the mean absolute deviation of the following dataset. Round your answer to the nearest tenth. {134,138,150,155,158,165} (1 point)
