A New Theoretical Interpretation of Measurement Error and Its Uncertainty
Table 6
Conceptual logic difference between the two theories.
Traditional measurement theory
New conceptual measurement theory
The measured value is a random variable because it changes randomly in repeated measurements
The measured value is a numeric value and is a constant
The true value is a constant because it remains constant during repeated measurements
The true value is unknown and is a random variable that needs to be described by a probability range
The best measured value is given by random error analysis
The best measured value is given by analyzing the randomness of errors
With the true value as the reference center, submit the evaluation of the deviation and dispersion (reproducibility) of the measured value
With the measured value as the reference center, submit the evaluation value of the probability range that the true value deviates from the measured value
The errors are divided into systematic and random classifications
The errors are not divided into systematic and random classifications
