Meaning of Accuracy
What is Accuracy:
Accuracy is the quality of conforming or approaching what is considered true.
The word accuracy derives from Latin exactus that means something punctual, and has the suffix -tud that indicates quality.
Accuracy is a correct and true definition of something. For example, "The experts defined exactly the consequences of the crisis."
In science, accuracy refers to how close the measured results are to the reference value, called the true value. As an example, we can consider that accuracy is how close a dart is to the target.
In any research project, based on the scientific method, a sufficient amount of data and results must be collected to corroborate the accuracy of the hypothesis raised.
See also Research project.
Synonyms of accuracy are similarity, correspondence, truthfulness, certainty, punctuality.
Measurement instrument accuracy
Accuracy in measuring instruments refers to how close the measured results are to the reference value, also called true value or true magnitude.
The accuracy depends on the quality of the calibration of the instrument that is studied by metrology. The accuracy of the results is precise, but the precise results are not necessarily exact, since the results may be concentrated but far from the true value.
Accuracy and precision
Generally speaking, accuracy and precision are used synonymously. In science, engineering, and metrology, these terms have different meanings.
Accuracy indicates a result that is close to the reference value or also called the true value or true magnitude. The closer to the true value, the more accurate the results.
Precision refers to the degree of dispersion of the results, the less dispersed the greater the precision.
