A measurement system can be accurate but not precise, precise but not accurate, neither, or both. For example, if an experiment contains a systematic error, then increasing the sample size generally increases precision but does not improve accuracy. The result would be a consistent yet inaccurate string of results from the flawed experiment.
A precising definition is intended to make a vague word more precise so that the word's meaning is not left to the interpretation of the reader or listener. Here is an example: From a class syllabus: "Class participation" means attending class, listening attentively, answering and asking questions, and participating in class discussions.
The precise meaning of a term given by a mathematical definition is often different from the English definition of the word used, [19] which can lead to confusion, particularly when the meanings are close. For example, a set is not exactly the same thing in mathematics and in common
The language of mathematics or mathematical language is an extension of the natural language (for example English) that is used in mathematics and in science for expressing results (scientific laws, theorems, proofs, logical deductions, etc.) with concision, precision and unambiguity.
In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
NIST Precision engineering research. Measurement of API Rotary Master Gauge on CMM. [1]Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time.
Terminology is a group of specialized words and respective meanings in a particular field, and also the study of such terms and their use; [1] the latter meaning is also known as terminology science. A term is a word, compound word , or multi-word expression that in specific contexts is given specific meanings—these may deviate from the ...
When an adjective can appear in both positions, the precise meaning may depend on the position. E.g. in French: un grand homme - "a great man" un homme grand - "a tall man" une fille petite - "a small girl" une petite fille - "a little girl" un petit chien - "a little dog (of a small breed)" un chien petit - "a small dog (for its breed)"
