Reinterpret the concept of measurement uncertainty
首发时间:2018-07-26
Abstract:The existing definition of uncertainty actually violates a basic mathematical concept: the variance of a constant with a definite value is 0. Therefore, various interpretations of uncertainty concept are actually specious. From the perspective of probability theory, this paper will point out the key trouble of existing concept, and fully prove that the uncertainty is actually the evaluation value of probability interval of an error and expresses the possible degree that the measured quantity value is close to the true value, instead of the dispersion of measured quantity value. This will lead to a comprehensive change in the interpretation method of measurement theory.
