(From Wikipedia, the free Encyclopedia)
In a common analogy illustrating the difference between accuracy and precision, repeated measurements are compared to arrows that are fired at a target. Accuracy describes the closeness of arrows to the bullseye at the target center. Arrows that strike closer to the bullseye are considered more accurate. The closer a system's measurements to the accepted value, the more accurate the system is considered to be.
To continue the analogy, precision would be size of the arrow cluster. When all arrows are grouped tightly together, the cluster is considered precise since they all struck close to the same spot, if not necessarily near the bullseye. The measurements are reproducible, though not necessarily accurate.
Ideally a measurement device is both accurate and precise, with measurements all close to and tightly clustered around the known value.
National standards organizations maintain weights and measures by which the accuracy of scientific and industrial devices are judged.

Screenplays | Our speedometer has melted and as a result it's very hard to see with any degree of accuracy exactly how fast we were going. (Planes, Trains & Automobiles; writing credit: John Hughes.) When one considers the Moon is 240,000 miles away and the Sun ninety-three million, it is an extraordinary thing that astronomers can tell with such a degree of accuracy what their movements will be many years ahead.
