(Askeri) reliability
The quality of a measurement indicating the degree to which the measure is consistent, that is, repeated measurements would give the same result (See validity)
The quality of being reliable, dependable, or trustworthy
{i} credibility, dependability, trustworthiness
the degree of performance of the elements of the bulk electric system that results in electricity being delivered to customers within accepted standards and in the amount desired May be measured by the frequency, duration, and magnitude of adverse effects on the electric supply
The assurance that a component will perform in a specified manner for a specified time under a set of specified conditions that include electrical, mechanical, thermal, and environmental stresses The concept of reliability encompasses the elements of both quality and longevity See STABILITY
The capability of a computer, or information or telecommunications system, to perform consistently and precisely according to its specifications and design requirements, and to do so with high confidence
An indication of how consistent test scores will be, given different testing conditions or editions of a test A test or measure is reliable when it is consistent (i e , repeated measurements would show the same achievement or several observers of a classroom situation would closely agree with ratings recorded for individuals on the same criterion)
The extent to which an experiment, test, or other measuring procedure yields the same results on repeated trials
The extent to which different operationalisations of the same concept produce consistent results To provide results that are statistically reliable a reasonably large and representative sample is required
the trait of being dependable or reliable
The ability of an item to perform a required function under stated conditions for a stated period of time NOTE: The term reliability is also used as a reliability characteristic denoting a probability of success, or a success ratio (a) Mission Reliability The ability of an item to perform its required mission critical functions for the duration of a specified mission or life profile (b) Basic Reliability The ability of an item to perform its required functions without failure for the duration of a specified mission profile ADDITIONAL NOTE: Usually, unless stated to the contrary, Reliability is deemed to include Durability
reliance on a friend in a time of need
Reliability refers to two technical criteria: consistency and "generalizability " The first criterion seeks consistency in results For example, will a student's score on a test today be close to his/her score tomorrow? "Generalizability" seeks to ensure that an assessment's questions that cover a subset of skills can capture or "generalize" a broader universe of skills
The degree to which the results of an assessment are dependable and consistently measure particular student knowledge and skills Reliability is an indication of the consistency of scores over time, between scores, or across different tasks or items that measure the same thing If scores from an assessment are unreliable interpretations based on these scores, and subsequent decisions, will not be valid
Extent to which a measurement (such as an instrument or a data collection procedure) produces consistent results over repeated observations or administrations of the instrument under the same conditions each time It is also important that reliability be maintained across data collectors (a concept called interrater reliability)
The quality of being reliable, dependable or trustworthy
The ability of an item to perform a required function under stated conditions for a stated period of time The numerical value of reliability is expressed as a probability from 0 to 1 and is also sometimes known as the probability of mission success Reliability is the probability, assuming the system was operating at time zero, that it continues to operate until time t
An indicator of score consistency over time or across multiple evaluators Reliable assessment is one in which the same answers receive the same score regardless of who performs the scoring or how or where the scoring takes place The same person is likely to get approximately the same score across multiple test administrations
The ability of the electric system to supply the electrical demand and energy requirements at all times and to withstand sudden disturbances such as electric short circuits or unanticipated loss of system facilities
The probability that an item can perform a required function under given conditions for a given time interval Note: It is assumed that the item is in a state to perform this required function at the beginning of the time interval
