Calculating coefficients of variation (CVs)

Calculating a coefficient of variation (CV) based on the margin of error is simple. You simply have to apply a formula. Calculate the CVs using this simplified formula from ESRI:

[ACS] = ACS Estimate Value

[MOE] = ACS Estimate Margin of Error Value

CV = Coefficient of Variation

CV = (([MOE]/1.645)/[ACS])*100

​

Image from the ESRI guide (linked above) showing the formula to calculate the CV. First, divide the MOE by 1.645, then divide this by the ACS estimate value. Multiple the resulting fraction by 100 to get the CV as a percentage.
