Question

what is the difference between Accuracy and Precision ?

Answer 1

Accuracy refers to the closeness of a measured value to a standard or known value. ... 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. You can be very precise but inaccurate, as described above.

Answer 2

Accuracy means perfectness but Precision means that it's not perfect
