Question

The difference between accuracy and precision

Answer 1

Accuracy refers to how close measurements are to the "true" value, while precision refers to how close measurements are to each other.

Answer 2

Accuracy is the degree of closeness between a measurement and the measurement's true value. Precision is the degree to which repeated measurements under the same conditions are unchanged.

Definition With Example

Accuracy refers to the closeness of a measured value to a standard or known value. ... 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.
