What is Percent of Error?

Back

Percent of Error is a measure of how inaccurate a measurement is, expressed as a percentage of the actual value. It is calculated using the formula: Percent of Error = |Estimated Value - Actual Value| / Actual Value × 100%.

How do you calculate Percent of Error?

Back

To calculate Percent of 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.

If you estimate a value of 50 and the actual value is 40, what is the Percent of Error?

Back

Percent of Error = |50 - 40| / 40 × 100% = 25%.

Front

What is the formula for calculating Percent of Error?

Back

Percent of Error = |Estimated Value - Actual Value| / Actual Value × 100%.
