Accuracy

What is meant by accuracy of a measurement is large or small deviation measurement results to the true value. If the difference is very small then it is said that the measurements are very accurate, and vice versa if the difference is large then it is said that the measurements are not accurate. The real value is never anyone knows, there is only approximate.

Value approach can be obtained by :

1. Averaging as much as possible the results of measurements

2. Determine how and where sampling test results are considered as the true value (eg stopped belt).
