Percent Error

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%.

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.

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

Percent Error = |(8 - 10)| / |10| × 100% = 20%.

Percent Error = |(35 - 28)| / |28| × 100% = 25%.

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

Percent Error = |(60 - 45)| / |60| × 100% = 25%.

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 and actual values, suggesting that the estimation was not accurate.

A low Percent Error indicates that the estimated value is close to the actual value, suggesting a more accurate estimation.
