What is Percent Error?
Percent error measures the accuracy of a measurement compared to a true or accepted value. It is calculated as the absolute difference between the observed and accepted values, divided by the accepted value, then multiplied by 100.
FORMULA
Percent Error =×100%
|Observed Value − Accepted Value|
Accepted Value
Percent Error =
|Observed Value − Accepted Value|
Accepted Value
× 100%
Alternative form:
Percent Error = |(Observed - Accepted)| / Accepted × 100%
