1. The differences in observed accuracy and/or precision experienced over the range of measurements made by the system.
2. The difference between observed measurements and a "true" value obtained from a master or gold standard
3. Different levels of variability in different operating regimes, resulting from warm-up effects, environmental factors, inconsistent operator performance
4. None of the above
- b. The difference between observed measurements and a "true" value obtained from a master or gold standard
