GENERAL KNOWLEDGE

Detailed explanation-1: -Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise. Precision is independent of accuracy.

Detailed explanation-2: -Precision shows the closeness of two or more measurements that they have to each other. It is certainly different from accuracy. Accuracy refers to the closeness of the measurements related to a specific value.

Detailed explanation-3: -The precision of the measurements refers to the spread of the measured values. One way to analyze the precision of the measurements would be to determine the range, or difference, between the lowest and the highest measured values.

Detailed explanation-4: -Precision refers to the amount of information that is conveyed by a number in terms of its digits; it shows the closeness of two or more measurements to each other. It is independent of accuracy.

Detailed explanation-5: -Arithmetic precision-number of significant digits for a value. Stochastic precision-probability distribution of possible values.
