Detailed explanation-1: -The ability of an instrument to measure the accurate value is known as accuracy. In other words, it is the the closeness of the measured value to a standard or true value. Accuracy is obtained by taking small readings.
Detailed explanation-2: -Precision is the closeness of a measurement to an accepted value.
Detailed explanation-3: -Accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value. Measurements that are both precise and accurate are repeatable and very close to true values.
Detailed explanation-4: -The accepted value definition is any numerical value that is widely considered to be accurate and are used without having been specifically re-measured.
Detailed explanation-5: -Accuracy is a measure of the closeness of an experimental value to the true or accepted value of the property being measured. If the true value is unknown, then a highly precise value is usually considered to be accurate, but beware of systematic or determinate errors.
