What is an acceptable range for the Coefficient of Dispersion (COD) when measuring uniformity of residential property?

The Coefficient of Dispersion (COD) is a statistical measure used to assess the uniformity of property assessments within a jurisdiction. It provides insight into the level of variability in property assessments relative to their market values. A lower COD indicates more uniform assessments, while a higher COD suggests greater variability.

An acceptable range for the COD in residential property assessments typically falls between 0 and 0.150. This range indicates that the assessments are reasonably consistent relative to the market values, which is crucial for ensuring fairness in taxation and promoting confidence in the assessment process. While it's possible to have COD values greater than 0.150, these would typically indicate a lack of uniformity, which can lead to concerns about equity among property owners.

Therefore, the choice of 0 to 0.150 as the acceptable range effectively reflects the industry's standards for uniformity in assessment practices, making it the correct answer in this context.
