Absolute Error


The difference between the measured or inferred value of a quantity x_0 and its actual value x, given by

 Deltax=x_0-x

(sometimes with the absolute value taken) is called the absolute error. The absolute error of the sum or difference of a number of quantities is less than or equal to the sum of their absolute errors.
