What is the fundamental difference between "Accuracy" and "Precision" in laboratory measurements?

• Accuracy only applies to instrument calibration, while precision applies to sample analysis.
• They mean the exact same thing in laboratory analytics.
• Accuracy is how close repeated measurements are to each other; Precision is how close they are to the true value.
• Accuracy is how close a measurement is to the true value; Precision is how close repeated measurements are to each other.
