COD - Coefficient of Dispersion: measures assessment equity between taxpayers in a municipality. The COD is calculated by dividing the average absolute deviation of each individual ratio from the overall median by the median ratio itself. The smaller this number is, the better the equity. An acceptable guideline of 20.0 or less has been established by the New Hampshire Assessing Standards Board.

PRD - Price Related Differential: This statistic measures the equity between taxpayers owning high-value properties versus taxpayers owning low-value properties. The PRD is calculated by simply dividing the mean ratio by the weighted mean ratio. If the result is a number greater than 1.0, then the higher value properties are being assessed at lower ratios than lower value. If the result is less than 1.0, the opposite is true.
