Relative percent difference definition
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 means the comparative statistic that is used to calculate precision or random error. RPD is calculated using the following equation:

More Definitions of Relative percent difference
Relative percent difference or “RPD” means a statistic used to evaluate the difference between two measurements when there is no evidence to support one being more accurate than the other. The RPD normalizes the difference between two measurements by dividing by the best estimate of the true value, which in this case is the mean of the two results. The difference is normalized, 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 precision.
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.
