refers to a measure of the dispersion of scores obtained by finding the average absolute difference (see absolute value) between each score and the average value for a particular group.

AVERAGE ABSOLUTE DEVIATION: "In any group of data, the average is found, and the average absolute deviation is calculated by adding up the absolute deviation of each score from that average, and then dividing the total by the number of cases."
