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 Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of Pre-Algebra to Algebra 2? For example, suppose that Dick balances on his head a flea (ick!) instead of Jane. weblink

Absolute Error and Relative Error: Error in measurement may be represented by the actual amount of error, or by a ratio comparing the error to the size of the measurement.
