A noticeable or marked departure from the norm, plan, standard, procedure, or variable being reviewed. Similar to variance.

A change from the standard form or published rates of an insurer.

Difference between an instantaneous value of a controlled variable and the desired value of the controlled variable corresponding to the set point. Also called an error.

The term deviation depending on the context it is used has varied meanings. Generally it means a change from a customary or agreed course of action. It is the noun form of the verb deviate.
