purpose
Accuracy: used to indicate the measurement results systematic error and Accidental error The degree of size The closeness between the average value of multiple measurements and the true value.
Measured value and True value The degree of closeness is called accuracy, and the difference between the two is called error. Accuracy is usually expressed by error. The smaller the error, the higher the accuracy of the analysis results. Accuracy depends on system error and Accidental error , indicating the correctness of the measurement results.
