What is the Difference Between Precision and Accuracy?

Many vendors of oceanographic instrumentation refer to accuracy and precision interchangeably. They are not interchangeable. In effect, accuracy refers to how well a sensor performs against a known third party standard. For example, a temperature sensor may be +/- 0.001 C, as compared to a Black Stack themistor module. Precision refers to the repeatability of the readings of a given sensor. A sensor is precise when it repeatedly provides the same reading, regardless of how accurate that reading is.

A good analogy is a dart board. The thrower of darts is accurate when he or she is able to reach the target, the bulls-eye. He or she is precise if, having thrown three darts, all three land in the same location, irrespective of whether or not that location is the bulls-eye.
