Relative percent difference definition

Relative percent difference means the comparative statistic that is used to calculate precision or random error. RPD is calculated using the following equation:
Relative percent difference or “RPD” means a comparative statistic used to calculate precision or random error. RPD is calculated using the following equation: RPD = absolute value (primary sample measurement - duplicate sample measurement) / ([primary sample measurement + duplicate sample measurement] / 2) × 100.
Relative percent difference or “RPD” means a comparative statistic used to calculate precision or random error. RPD is calculated using the following equation: RPD = absolute value (primary sample

More Definitions of Relative percent difference

Relative percent difference or “RPD” means a statistic used to evaluate the difference between two measurements. The “RPD” normalizes the difference between two measurements by dividing by the best estimate of the true value, which is the mean of the two results. The difference is compared as a fraction to the mean of the two results as there is no reason to assume that one measurement is more accurate than the other, and over time a set of “RPD” values can be used as an estimate of imprecision.
Relative percent difference means a statistical analysis between two measurements defined as the absolute difference between the two measurements, divided by their average, then converted to percentage.
