Percent Error

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

To calculate Percent Error, use the formula: Percent Error = |(Estimated Value - Actual Value)| / |Actual Value| * 100.

Percent Error = |(15,000 - 12,500)| / |12,500| * 100 = 20%.

Percent Error = |(17,600 - 21,300)| / |21,300| * 100 = 17.4%.

A percent error of 0% indicates that the estimated value is exactly equal to the actual value, meaning there is no error.

A high percent error indicates a large discrepancy between the estimated value and the actual value, suggesting that the estimation was not accurate.

Percent Error = |(520 - 500)| / |500| * 100 = 4%.

To round percent error to the nearest tenth, look at the hundredths place. If it is 5 or greater, round up the tenths place by one.

Percent Error = |(35 - 38)| / |38| * 100 = 7.9%.

Percent Error = |(12 - 14.25)| / |14.25| * 100 = 15.79%.
