A test-retest study is performed to a coordinate measuring machine (CMM) using a working standard...

The correction for the CMM is determined by the difference between the measured mean and the standard value.

The necessary correction is calculated as follows:Correction=Standard Value−Measured Mean\text{Correction} = \text{Standard Value} - \text{Measured Mean}Correction=Standard Value−Measured MeanCorrection=100.00−107.88=−7.88 mm\text{Correction} = 100.00 - 107.88 = -7.88 \text{ mm}Correction=100.00−107.88=−7.88 mm

The correction should be applied in such a way to adjust the measurements to the standard value.
