| coefficient of variation |
(CV) the standard deviation divided by the mean, sometimes multiplied by 100; a unitless quantity indicating the variability around the mean in relation to the size of the mean.

The coefficient of variation (CV) indicates the quality of a population estimate. A CV of 16.7-25.5 indicates moderate sampling variability. A CV of 25.6-33.3 indicates high sampling variability. Estimates with either a moderate or high CV should be interpreted with caution. In some situations, the sample in the survey was too small to produce a reliable estimate. These numbers are not included in the report.

| coefficient of variation |
The measure of the ability to repeatedly obtain the same value for a single sample or method (ie; duplicate or replicate analyses). This may also be called the precision. [Note: Accuracy is not the point here, but rather how many times the same answer is obtained when all factors of the analysis remain constant ?same sample, same volume, same method, etc.] This value is calculated the same as a Relative Standard Deviation.

| coefficient of variation |
The ratio of the standard error for a variable to the mean value of the variable. This is used to measure the imprecision in survey estimates introduced by sampling. A coefficient of variation of 1 percent would indicate that an estimate could vary slightly due to sampling error, while a coefficient of variation of 50 percent means that the estimate is very imprecise. ...
