How do you find the mean from the absolute deveation?

To find the mean from the absolute deviation, you first need to have the set of data points from which the absolute deviations were calculated. The absolute deviation is the absolute difference between each data point and the mean. To find the mean, sum all the data points and divide by the number of points, which gives you the average value. The absolute deviation can then be used to assess how much the data points deviate from this calculated mean.
