1. Whenever a gauge is used to take measurements, two components comprise the value that
was obtained. One is the actual value of the dimensions plus the errors relating to the
ability of the gauging system to measure the dimension. The difference is brought by the
probable error when using the gauge. The issue in this case is accuracy. Observed values
may be different from the true value of an item’s dimension.
2. Precision is the aspect of measurement that addresses repeatability or consistency when
an identical item is measured several times. It is possible to have a very precise
measurement with the absence of scatter (or noise) which is repeatable that can be
considered as precise (repeatable). But accuracy is questionable because of an instrument
error. On the other hand, accuracy is the characteristic of measu...
