#"Accuracy is the closeness of a measurement to the true value."#


Whereas #"precision"# is the repeatability of the measurement. For example, a stopped clock is ACCURATE twice a day; however, it is not very precise.

Precise measurements may be inaccurate, and an accurate measurement maybe highly imprecise...you should read your analytical text...
