Answer:

The mean absolute deviation is 16.

Explanation:

For a set of N values:

{x₁, x₂, ..., xₙ}

The mean value is:


M = (x_1 + x_2 + ... + x_n)/(N)

And the mean absolute deviation is:


MAD = (|x_1 - M| + |x_2 - M| + ... + |x_n - M|)/(N)

In this case, we have a set of 4 values, {-32, 9, 11, 12}

The first thing we need to do is find the mean, it will be equal to:


M = (-32 + 9 + 11 + 12)/(4) = 0

Then the mean absolute deviation will be:


MAD = (|-32 - 0| + |9 - 0| + |11 - 0| + |12 - 0 |)/(4) = (32 + 9 + 11 + 12)/(4) = 16

The mean absolute deviation is 16.
