QC The Calculations Westgard Therefore, it is best to calculate the CV from the observed results at 190 mg dL, then apply that CV to the 200 mg dL decision level. This is the reason that QC planning applications with the QC Validator program use a percentage figure for the imprecision of the method. Z 4: Mean, Standard Deviation, And Coefficient Of Variation Coefficient of variation. Another way to describe the variation of a test is calculate the coefficient of variation, or CV. The CV expresses the variation as a percentage of the mean, and is calculated as follows: CV% = (SD Xbar)100. In the laboratory, the CV is preferred when the SD increases in proportion to concentration.
