The formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value. 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 What Is A Good Percent Error Yes No Can you tell us more?
