What is acceptable coefficient of variation?

What is acceptable coefficient of variation?

Basically CVacceptable, and CV>30 is not acceptable.

What is CV in laboratory?

The coefficient of variation (CV) is calculated as the standard deviation (SD) divided by the mean and multiplied by 100. CV indicates variability of the test results. This depends upon the test methodology, the instrument being used, and the range of results.

What is CV% of count?

The relative count gives the mass deviation in % of the whole test length of each test sample as compared to the average mass of all samples. This value is an indication of relative count deviation (CV). The variation of the yarn count (CV count) is the variation from one bobbin to the other.

How do you calculate SD on CV?

If you know nothing about the data other than the mean, one way to interpret the relative magnitude of the standard deviation is to divide it by the mean. This is called the coefficient of variation. For example, if the mean is 80 and standard deviation is 12, the cv = 12/80 = . 15 or 15%.
