ACCURACY AND PERCISION 1 Accuracy and Precision Accuracy and precision both relate to the quality of a measure.

The meaning of accuracy is the extent to which a given measurement agrees with the standard value for that measurement. The meaning of precision is the degree to which the correctness of a quantity is articulated. The difference between accuracy and precision is like playing a game of darts. There can have several outcomes by shooting three arrows. If all three arrows hit the bulls’ eye, this would show accuracy and precision. If all three arrows hit the dartboard near each other but not in the bulls’ eye, which would show precise, except not accurate.

Today, society depends on the accuracy and precision of measurements for products sold
