What is percent error?

Back

Percent error is a measure of how inaccurate a measurement is, compared to the true value. It is calculated using the formula: Percent Error = |(Estimated Value - Actual Value)| / |Actual Value| * 100%.

Front

How do you calculate percent error?

Back

To calculate percent error, subtract the actual value from the estimated value, take the absolute value of the result, divide by the actual value, and then multiply by 100 to get a percentage.
