What’s The Difference Between Precision And Accuracy

Heidenhain High Accuracy Gages

When taking data measurements, precision and accuracy are two most important factors to consider. Both of them reflect how close we are to getting an actual value. However, there is a slight difference between the two. Precision gives the reproducibility of the measurements, even if they are nowhere near to the accepted value. Accuracy gives a number close to that of accepted or known value. It’s like hitting a bullseye. Measurements which are both accurate and precise are very near to actual values, and can be repeated.
