Because actual rather than absolute values of the forecast errors are used in the formula, positive and negative forecast errors can offset each other; as a result the formula can be Absolute Error Formula Approximate Value − Exact Value × 100% Exact Value Example: They forecast 20 mm of rain, but we really got 25 mm. 20 − 25 25 × 100% = −5 25 The precision of a measuring instrument is determined by the smallest unit to which it can measure. weblink Absolute, Relative and Percentage Error The Absolute Error is the difference between the actual and measured value But ...
