Explanation: 

Detailed explanation-1: -Accuracy refers to the closeness of a measured value to a standard or known value. For example, if in lab you obtain a weight measurement of 3.2 kg for a given substance, but the actual or known weight is 10 kg, then your measurement is not accurate. In this case, your measurement is not close to the known value.

Detailed explanation-2: -Accuracy refers to the closeness of the measured value to a standard or true value.

Detailed explanation-3: -Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy.

Detailed explanation-4: -Accuracy is the closeness of value and true value.
