Description: |
The Variance calibration variable is the average deviation of all area values F from the corresponding ideal area value in a calibration. The ideal area value is the value at the point of intersection between the calculated calibration curve and the corresponding amount value. Variance is therefore a criterion for the measuring accuracy in the calibration. With an increasing value, calibration points are increasingly scattered. |

Note:
|
Extracting the square root of the variance value results in the Standard Deviation calibration variable; that is, the square standard deviation is the variance. |
