Explanation

Percent error measures how far a measured value is from the accepted or true value, relative to that accepted value. A smaller percent error means the measurement is closer to the true value, so it indicates accuracy. The median and range describe data distributions, while precision concerns how closely repeated measurements agree with one another.
