Abstract
The equivalence principle of unequal precision measurement and its statistical method are presented in detail.The application of the principle and its method is also instantiated by the example of measuring the resistance of a resistor with the internal connection and external connection method.The example shows that the equivalence principle of unequal precision measurement together with it.Its statistical method can be used as a quantitative criterion for judging the advantages and disadvantages of different methods of measuring the same physical quantity.
