Percent Error Practice

Percent 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 Error = |(Estimated Value - Actual Value)| / |Actual Value| * 100.

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 multiply by 100.

Percent Error = |(Estimated Value - Actual Value)| / |Actual Value| * 100.

15.79%.

A percent error of 0% indicates that the estimated value is exactly equal to the actual value.

Calculating percent error helps to assess the accuracy of measurements and estimates, which is crucial in scientific experiments and real-world applications.
