Percent error or percentage error expresses as a percentage the difference between an approximate or measured value and an exact or known value. It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value. Here is how to calculate negative percent error percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value. The absolute value of the error is divided by an accepted value and given as a percent.|accepted value - experimental value| \ accepted value x 100%Note for chemistry and other sciences, it is customary to keep a negative value. Whether error is positive or negative is important. For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation StepsSubtract one value from another. The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs. This value is your 'error'. continue reading below our video 4 Tips for Improving Test Performance Divide the error by the exact or ideal value (i.e., not your experimental or measured value). This will give you a decimal number. Convert the decimal number into a percentage by multiplying

correct, accepted or exact value. Outputs/Solution: Percent Error - Percent error is the absolute value of the difference of the measured value and the http://chemistry.about.com/od/workedchemistryproblems/a/percenterror.htm actual value divided by the actual value and multiplied by 100. A small error means the measured value is close to the actual value. A large error means there may be something wrong with the experiment or equipment. Note, this calculator uses the absolute value method for error calculation. http://www.percenterrorcalculator.com/ The absolute value of a negative number will turn it positive.
