Which of the following measures indicates the uniformity of equity?

The coefficient of variation is a valuable measure when assessing the uniformity of equity in mass appraisal. It provides insights into the dispersion of property values relative to the mean. This metric is particularly useful because it expresses the variability of the ratios (the relationship between assessed values and market values) as a percentage of the mean ratio, facilitating comparisons across different datasets or groups of properties.

A lower coefficient of variation indicates that the assessed values are more consistent and equitable among properties, while a higher coefficient suggests greater disparities. This statistical tool enables assessors to pinpoint inconsistencies in property valuations and identify areas for improvement in maintaining equitable assessments across a jurisdiction.

While other measures like the median ratio and mean ratio provide information about central tendency and individual assessment levels, they do not fully capture the variability or distribution of those assessments relative to the overall average. Range analysis indicates the spread between the highest and lowest values but does not offer a normalized measure of variability in relation to the mean, either. Therefore, the coefficient of variation stands out as the most effective choice for measuring uniformity of equity in mass appraisal contexts.
