Accuracy
Measure of exactness, possibly expressed in percent; Compare: precision

Accuracy
A performance criterion that describes the degree of correctness with which a function is performed. (The function may or may not be performed with the desired speed.) (source: ITU-T I.350).

Telecommunication Standard Terms
accuracy
The degree of conformity of a measured or calculated value to its actual or specified value. Contrast with precision.

Accuracy
The combined error of nonlinearity, repeatability, and hysteresis expressed as a percent of full scale output.

General Chemistry Glossary
accuracy
 Say it 
Compare with precision and trueness .Accuracy is the correctness of a single measurement. The accuracy of a measurement is assessed by comparing the measurement with the true or accepted value, based on evidence independent of the measurement. The closeness of an average to a true value is referred to as "trueness".

Glossary of Cartographic Terms
accuracy
Degree of conformity with a standard. Accuracy relates to the quality of a result and is distinguished from precision which relates to the quality of the operation by which the result is obtained.

Accuracy
The use of the word "accurate" - free of error - in referring to a scientific observation or scientific method sometimes obscures the fact that even the best methods and observations are only relatively free from error. The use of the single word "accurate" also hides the fact that a number of separate elements contribute to over-all freedom from error. "Accurate" is frequently used to refer indiscriminately to the effect of any of these elements, or to the combined effects of all of them on the freedom from error of a system. Effective use of a method or observation requires that we know the ways and degrees to which the data are free of error, not that we know only that the data are "accurate" or "inaccurate".

The elements to be taken into account in a complete evaluation of a method or system can be derived from the properties of the quantitative relationship between the "input" and the "output" for the system. The input-output relationship, for all its generality, has specific application--and specific names--in different scientific fields and for different kinds of experimental or observational systems. In physics and engineering, the "stress-strain diagram" is a special
representation of the input-output relationship; in pharmacology, the "dose-effect curve" is an example of the input-output relationship. In quantitative chemical analyses, the "calibration curve" is an example of the input-output relationship. Generally, "input" can be looked on as the measured value of an independent variable or "measurand"; "output" can be viewed as a measurement made under non-standard or test conditions.

"Accuracy", as formally defined, and the elements that contribute to it can be only briefly outlined here.

Accuracy
In engineering, "accuracy" is the ratio of the "error" of a system to the range of values for output that are possible, i.e., the ratio of error to so-called Full-Scale Output. Error is defined as the algebraic difference between an indicated output value and the true measure of the input or measurand. Error, as defined by the engineer, is most like "precision" as defined below.
Validity
The degree to which output reflects what it purports to reflect, i.e., input; the degree to which output is a function of known input and it alone. For example, does an essay examination validly measure a student's knowledge of material, or is it invalid, actually measuring his literary skill or the state of the grader's digestion?
Reliability
The degree to which the input-output relationship is reproducible if the relationship is studied repeatedly under comparable conditions. For example, if a student took the same examination twice, or in two forms, would he get the same grade both times? If the same work were reviewed by two graders, would they both assign the same mark?
Sensitivity
The lowest value of input that can be inferred with a given degree of
validity and reliability from measurements of output. Analogous to the usage for the word "threshold" is the phrase "threshold dose". The engineer uses the word "threshold", however, to mean the smallest change in input that will result in change in output.
Amplification
The amount of change in measured output per unit change in input. The slope of the input-output, or dose-effect, curve. (Engineers sometimes refer to "amplification" as "sensitivity".)

Accuracy Definition from Encyclopedia Dictionaries & Glossaries

Wikipedia English - The Free Encyclopedia
Accuracy and precision
In the fields of scienceengineeringindustry and statistics, accuracy is the degree of conformity of a measured or calculated quantity to its actual (true) value. Accuracy is closely related to precision, also called reproducibility or repeatability, the degree to which further measurements or calculations show the same or similar results. The results of calculations or a measurement can be accurate but not precise; precise but not accurate; neither; or both. A result is called valid if it is both accurate and precise. The related terms in surveying are error (random variability in research) and bias (non-random or directed effects caused by a factor or factors unrelated by the independent variable).
