Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:

The mean absolute deviation is:

And the population standard deviation is:

In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:

The mean absolute deviation is:

And the population standard deviation is:
