If the mean value of the data set is 509. Then the mean absolute deviation (MAD) for the data set will be 51.5.
<h3>What is the mean absolute deviation?</h3>
It is the average distance between each data point and the mean.
The mean of the following data is 509.
{419, 450, 462, 499, 520, 521, 589, 612}
Then the mean absolute deviation (MAD) for the data set will be

We have
μ = 509
n = 8
Then
