The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. [3] [4] Although the two words precision and accuracy can be synonymous in colloquial use, they are deliberately contrasted in the context of the scientific method.
A precising definition is a definition that contracts or reduces the scope of the lexical definition of a term for a specific purpose by including additional criteria that narrow down the set of things meeting the definition.
These title criteria are not theoretical at all, but pure-practicality matters of clarity in writing and in information architecture. Philosophy arguments about proper names are confusing to the vast majority of editors, who are steeped necessarily in the more applicable linguistic sense of proper name (and the most everyday version of that sense).
In information retrieval, the positive predictive value is called precision, and sensitivity is called recall. Unlike the Specificity vs Sensitivity tradeoff, these measures are both independent of the number of true negatives, which is generally unknown and much larger than the actual numbers of relevant and retrieved documents.
The purpose of testing involves a prior determination of expected observation and a comparison of that expectation to what one actually observes. [5] The results of testing can be qualitative (yes/no), quantitative (a measured value), or categorical and can be derived from personal observation or the output of a precision measuring instrument .
