What does COD stand for in statistical measurement?

The term "COD" in statistical measurement stands for Coefficient of Dispersion. This measure evaluates the level of uniformity of property assessments, particularly in mass appraisal contexts. It provides insight into how closely the assessed values align with their market values. A lower coefficient indicates assessments that are more consistent or uniform, while a higher coefficient suggests greater variability among assessments.

The Coefficient of Determination, while it relates to statistical analysis, specifically measures the proportion of variance in a dependent variable that can be predicted from an independent variable, and is not directly applicable to the context of assessment equity. Options like Center of Data, Count of Discrepancies, and Condition of Data do not represent established statistical measures within mass appraisal frameworks. Recognizing the correct term helps practitioners and students apply appropriate statistical tools for evaluating appraisal quality and equity.
