What is Accuracy?
Accuracy is the degree of closeness of a measured or calculated value to the true or accepted value of the quantity being measured. It is distinct from precision, which refers to reproducibility of measurements. A highly accurate measurement is close to the true value, regardless of how consistent repeated measurements are.
