Meaning of Precision (What is, Concept and Definition)

What is Precision:

Precision is the delimitation of a concept, variables or measures with minimal errors .

Precision derives from the Latin praecisio that indicates something that is well cut and delimited.

In the philosophical sense, precision is the mental abstraction that separates and defines concepts in order to differentiate them from others.For example, the The difference between freedom and debauchery has a similar basis but freedom is limited in respect for others while debauchery is defined by the abuse of freedom.

Precision refers to the execution of some of the a form that was planned as, for example, military precision.It can also be used to refer to an object that performs exactly in the desired way, such as a precision knife or a precision balance.

Precision in measuring instruments

In physics, chemistry and science in general, precision refers to the degree of closeness that present the results obtained from the control of the same conditions.

In this sense, the precision is associated with the sensitivity of the instrument.The greater the precision of the instrument, the greater the proximity of the results with in relation to the different measurements made with the same parameters.

An instrument with precision must be correctly calibrated according to the variables that the environment is used in.The field that studies the calibration procedures, measurement methods and its different instruments is called metrology.

In chemistry, for example, the calibration of instruments such as the analytical balance to measure weight, and the dynamometer, to measure the mass of an object or substance, are essential for precision results.

Precision and accuracy

In general, the words precision and accuracy can be used as synonyms.change, in scientific, statistical and measurement, the concepts of precision and accuracy have different meanings.

Precision refers to the proximity of the values ​​obtained by applying the same parameters, but accuracy is the degree of coincidence between the average value of the results obtained with the value defined as a reference.

For example, if we look through a digital positioning system: “Zocalo, Mexico City” defining the most important square in the city as the place of reference , the system can yield results from the Zocalo metro, the historic center, the surrounding streets, a restaurant, a newspaper, etc.The result is accurate if you approach the reference point and it would not be precise as you move further away from the square.The result is accurate if it indicates the Constitution Square of Mexico City.

Precision in a text

The precision is part of the writing and style techniques of a t exto.Especially in expository, informative and scientific texts, precision is important for the clarity and objectivity of the information.

The precision of a text indicates the correct use of grammar, punctuation and spelling.In addition, special care must be taken in the use of corresponding terms that accurately express the meaning that is intended to be presented.

All text must be clear, precise and concise, that is, without ambiguity, accuracy in the expression of thought and words and brief exposition of what is strictly necessary.
