1.4.1 State differences between precision and accuracy.

S.No	Accuracy	Precision
1	Accuracy is a measure of rightness	Precision is a measure of exactness
2	Accurate means "capable of providing a correct reading or measurement."	Precise means “repeatable, reliable, getting the same measurement each time.”
3	A measurement is accurate if it correctly reflects the size of the thing being measured	Precision refers to how closely individual measurements agree with each other.
4	If your scale gives you values of 49.8, 50.5, 51.0, 49.6, it is more accurate than the first balance, but not as precise.	If you take the measurements of the mass of a 50.0-gram standard sample and get values of 47.5, 47.6, 47.5, and 47.7 grams, your scale is precise, but not very accurate.
5	It depends on the measurement not the device used for measurement.	It depends on the measuring instrument.
