Average absolute deviation
Knowing how much a given predicted value deviates from the actual value isn't all that useful by itself. Instead, you want to know which set of predictions is more accurate.
Fortunately, you can combine your knowledge of measures of central tendency with your practice with absolute deviations to see which predictions are more accurate.
