Accuracy and precision both relate to the quality of a measure. However‚ the terms have separate meanings and should not be applied as an alternate for the other. 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
