In statistics, the difference between one value and the mean of the set of values. Mean deviation is the mean of all the individual deviations of a set.

(DOD, NATO) 1. The distance by which a point of impact or burst misses the target. See also circular error probable; delivery error; dispersion error; horizontal error. 2. The angular difference between magnetic and compass headings.

i. The angular difference between a magnetic and a compass heading. It is a compass error caused by the compass magnet attempting to align with the aircraft’s local magnetic field. The deviation error changes with the aircraft heading and the latitude. It is measured in degrees east (+) or west (-), depending on whether the north-seeking end of the compass needle lies to the east or west of magnetic north.



ii. The angle between the wind and the pressure gradient.



iii. In frequency modulation, the amount the carrier increases or decreases when modulated.
