Hi There:
We did a bias study on a CMM machine using the reference value representing the expected range for the parts that are measured. The average bias is -0.0002" or 16% of the process variation (total variation row of the Study Var (6*SD) column from Gage R&R study). The P-value for the average bias is 0.0000. My questions are: What do I do with this information? Do I need to add 0.0002" to the measurements I obtain from the measurement system?
