Refimprove date May 2008 Objective precision Latin praecisio obiectiva is a philosophy philosophical term and concept used in scholasticism late and especially second scholasticism describing the objective aspect of abstraction . Objective precision is the process by which certain features the differentia e of the real object of a formal concept are excluded from the comprehension of that concept the object is thus being intentionally transformed into a universal objective concept . Objective precision is thus a process by which universal objective concepts arise, it is the objective aspect of the process of total abstraction or concept formation. Objective precision and formal precision Objective precision is distinguished against formal precision . Whereas objective precision is a process on the part of objective concepts the objective correlates of the mental acts by means of which something is being conceived formal precision is the corresponding process on the part of formal concepts or the mental acts themselves. Objective and formal precision are the two aspects objective and subjective of abstraction.

Refimprove date July 2010 Precision bias is a form of cognitive bias in which an evaluator of information commits a logical fallacy as the result of confusing accuracy and precision . More particularly, in assessing the merits of an argument, a measurement, or a report, an observer or assessor falls prey to precision bias when he or she believes that greater precision implies greater accuracy i.e., that simply because a statement is precise, it is also true . Precision bias, whether called by that phrase or another, is addressed in fields such as economics, in which there is a significant danger that a seemingly impressive quantity of statistics may be collected even though these statistics may be of little value for demonstrating any particular truth. It is also called the numeracy bias, or the range estimate aversion. The clustering illusion and the Texas sharpshooter fallacy may both be treated as relatives of precision bias. In these former fallacies, precision is mistakenly considered evidence of causation, when in fact the clustered information may actually be the result of randomness .

Unreferenced stub auto yes date December 2009 Orphan date December 2009 In agriculture , precision seeding is a method of seeding that involves placing seed at a precise spacing and depth. This is in contrast to broadcast seeding , where seed is scattered over an area. Although precise hand placement would qualify, precision seeding usually refers to a mechanical process. A wide range of hand push and powered precision seeders are available for small to large scale jobs. Using a variety of actions, they all open the soil, place the seed, then cover it, to create rows. The depth and spacing vary depending on the type of crop and the desired plant density. In commercial production, precision seeding is an alternative to placing larger quantities of seed in a row, by dribbling seed or setting several seeds in each position. Depending on the device, precision seeders may place only one, or a very few seeds per position. This is an advantage, in that it saves seed and it avoids crowding, or the need for thinning , allowing plants the space to grow efficiently. On the downside, by placing fewer seeds, a very high germination rate is required to make full use of the seeded area.

In statistics , the term precision can mean a quantity defined in a specific way. This is in addition to its more general meaning in the contexts of accuracy and precision and of precision and recall . There can be differences in usage of the term for particular statistical models but, in general statistical usage, the precision is defined to be the Multiplicative inverse reciprocal of the variance , while the precision matrix is the matrix inverse of the covariance matrix . ref name dodge Dodge Y. 2003 The Oxford Dictionary of Statistical Terms , OUP. ISBN 0 19 920613 9 ref One particular use of the precision matrix is in the context of Bayesian analysis of the multivariate normal distribution for example, Bernardo & Smith ref Bernardo, J.

Unreferenced date October 2009 The precision of a value describes the number of numerical digit digit s that are used to express that value. In a scientific setting this would be the total number of digits sometimes called the significant figures or significant digits or, less commonly, the number of fractional digits or decimal places the number of digits following the radix point point . This second definition is useful in financial and engineering applications where the number of digits in the fractional part has particular importance. In both cases, the term precision can be used to describe the position at which an inexact result will be rounded. For example, in floating point arithmetic, a result is rounded to a given or fixed precision, which is the length of the resulting significand . In financial calculations, a number is often rounded to a given number of places for example, to two places after the decimal separator for many world currencies . As an illustration, the decimal quantity 12.345 can be expressed with various numbers of significant digits or decimal places. If insufficient precision is available then the number is rounding rounded in some manner to fit the available precision.

refimprove date June 2006 False precision also called overprecision , fake precision , misplaced precision and spurious accuracy occurs when numerical data are presented in a manner that implies better Accuracy and precisionprecision than is actually the case since precision is a limit to accuracy, this often leads to overconfidence in the accuracy as well. ref cite web url http www.fallacyfiles.org fakeprec.html title Overprecision publisher Fallacy files ref In science and engineering , convention dictates that unless a margin of error is explicitly stated, the number of significant figures used in the presentation of data should be limited to what is warranted by the precision of those data. For example, if an instrument can be read to an accuracy of tenths of a unit of measurement, results of calculations using data obtained from that instrument can only be confidently stated to the tenths place, regardless of what the raw calculation returns or whether other data used in the calculation are more accurate. Even outside these disciplines, there is a tendency to assume that all the non zero digits of a number are meaningful thus, providing excessive figures may lead the viewer to expect better precision than actually exists. However, in contrast, it is good practice to retain more significant figures than this in the intermediate stages of a calculation, in order to avoid accumulated rounding errors.
