Uncertainty is a quantitative measure of how much your measured values deviate from a standard or expected value. Precision is the closeness of the results to others obtained in exactly. Precision refers to the reproducibility of a measurement. The accuracy of a measured quantity is its agreement with a standard or true value. Accuracy indicates how close a measurement is to the true or accepted value.
