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 .

This is in addition to its more general meaning in the contexts of accuracy and precision and of precision and recall .

. The number 0, to any precision, can be taken to be 0. See also False precisionAccuracy and precisionPrecision computer science Round off error IEEE754 IEEE floating point standard http www.amazon.com ...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.

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.
