Dell Precision is a series of computer workstations for computer-aided design/architecture/computer graphics professionals, or as small-scale business servers [citation needed]. They are available in both desktop (tower) and mobile (laptop) form.
Precision takes all retrieved documents into account. It can also be evaluated considering only the topmost results returned by the system using Precision@k. Note that the meaning and usage of "precision" in the field of information retrieval differs from the definition of accuracy and precision within other branches of science and statistics.
Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory.
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
Because of the complex inter-relationship between analytical method, sample concentration, limits of detection and method precision, the management of Analytical Quality Control is undertaken using a statistical approach to determine whether the results obtained lie within an acceptable statistical envelope.
Precision is how close the measurements are to each other. The International Organization for Standardization (ISO) defines a related measure: [1] trueness, "the closeness of agreement between the arithmetic mean of a large number of test results and the true or accepted reference value." According to ISO 5725-1, accuracy consists of trueness ...
OptiPlex (a portmanteau of "optimal" and "-plex") is a line of business-oriented desktop and all-in-one computers made for corporate enterprises, healthcare, the government, and education markets. Initially released in 1993 by Dell , these computers typically contain Intel CPUs , beginning with Celeron and Pentium and currently [update] with ...
If the correlation between separate administrations of the test is high (e.g. 0.7 or higher as in this Cronbach's alpha-internal consistency-table [6]), then it has good test–retest reliability. The repeatability coefficient is a precision measure which represents the value below which the absolute difference between two repeated test results ...
