The measured value given by any scientific measuring instruments is subject to some kind of errors. However, the reliability is assessed by the amount of error in the true value given by the instrument. Hence, it is necessary to identify the sources of errors and attempt shall be made to rectify them. As the true value of any measure may be function of several independent factors, therefore the impact of each independent factor, one by one, shall be examined on the true value keeping remaining factors constant.
