What is RELIABILITY THEORY? What does RELIABILITY THEORY mean? RELIABILITY THEORY meaning.
Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
Reliability theory describes the probability of a system completing its expected function during an interval of time. It is the basis of reliability engineering, which is an area of study focused on optimizing the reliability, or probability of successful functioning, of systems, such as airplanes, linear accelerators, and any other product. It developed apart from the mainstream of probability and statistics. It was originally a tool to help nineteenth century maritime insurance and life insurance companies compute fair-value rates to charge their customers. Even today, the terms "failure rate" and "hazard rate" are often used interchangeably.
The failure of mechanical devices such as ships, trains, and cars, is similar in many ways to the life or death of biological organisms. Statistical models appropriate for any of these topics are generically called "time-to-event" models. Death or failure is called an "event", and the goal is to project or forecast the rate of events for a given population or the probability of an event for an individual.
When reliability is considered from the perspective of the consumer of a technology or service, actual reliability measures may differ dramatically from perceived reliability. One bad experience can be magnified in the mind of the customer, inflating the perceived unreliability of the product. One plane crash where hundreds of passengers die will immediately instill fear in a large percentage of the flying consumer population, regardless of actual reliability data about the safety of air travel.
Reliability period of any object is measured within the durability period of that object.

Cal State Northridge Psy 320 Andrew Ainsworth, PhD Classical Test Theory and Reliability
,Basics of Classical Test Theory Theory and Assumptions
Types of Reliability Example ,Classical Test Theory Classical Test Theory (CTT) – often called the “true score model”
Called classic relative to Item Response Theory (IRT) which is a more modern approach CTT describes a set of psychometric procedures used to test items and scales reliability, difficulty, discrimination, etc. ,Classical Test Theory CTT analyses are the easiest and most widely used form of analyses. The statistics can be computed by readily available statistical packages (or even by hand)
CTT Analyses are performed on the test as a whole rather than on the item and although item statistics can be generated, they apply only to that group of students on that collection of items ,Classical Test Theory Assumes that every person has a true score on an item or a scale if we can only measure it directly without error
CTT analyses assumes that a person’s test score is comprised of their “true” score plus some measurement error. This is the common true score model ,Classical Test Theory Based on the expected values of each component for each person we can see that
E and X are random variables, t is constant However this is theoretical and not done at the individual level. ,Classical Test Theory If we assume that people are randomly selected then t becomes a random variable as well and we get:
Therefore, in CTT we assume that the error : Is normally distributed
Uncorrelated with true score Has a mean of Zero ,T X=T+E
,True Scores Measurement error around a T can be large or small
T1 T2 T3
,Domain Sampling Theory Another Central Component of CTT
Another way of thinking about populations and samples Domain - Population or universe of all possible items measuring a single concept or trait (theoretically infinite) Test – a sample of items from that universe ,Domain Sampling Theory A person’s true score would be obtained by having them respond to all items in the “universe” of items
We only see responses to the sample of items on the test So, reliability is the proportion of variance in the “universe” explained by the test variance ,Domain Sampling Theory A universe is made up of a (possibly infinitely) large number of items
So, as tests get longer they represent the domain better, therefore longer tests should have higher reliability Also, if we take multiple random samples from the population we can have a distribution of sample scores that represent the population ,Domain Sampling Theory Each random sample from the universe would be “randomly parallel” to each other
Unbiased estimate of reliability = correlation between test and true score
= average correlation between the test and all other randomly parallel tests ,Classical Test Theory Reliability Reliability is theoretically the correlation between a test-score and the true score, squared
Essentially the proportion of X that is T This can’t be measured directly so we use other methods to estimate ,CTT: Reliability Index Reliability can be viewed as a measure of consistency or how well as test “holds together”
Reliability is measured on a scale of 0-1. The greater the number the higher the reliability. ,CTT: Reliability Index The approach to estimating reliability depends on
Estimation of “true” score
Source of measurement error Types of reliability Test-retest
Parallel Forms Split-half Internal Consistency ,CTT: Test-Retest Reliability Evaluates the error associated with administering a test at two different times.
Time Sampling Error How-To: Give test at Time 1
Give SAME TEST at Time 2 Calculate r for the two scores • Easy to do; one test does it all. ,CTT: Test-Retest Reliability Assume 2 administrations X1 and X2
The correlation between the 2 administrations is the reliability ,CTT: Test-Retest Reliability Sources of error

Is knowledge a matter of being causally connected to the world in the right way? In this Wireless Philosophy video, Jennifer Nagel (University of Toronto) examines the causal theory of knowledge proposed by Alvin Goldman in 1967, and then discusses the problems with the causal theory that led Goldman to formulate his influential reliabilist theory of knowledge.

Theory
Theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might for example include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several different related meanings. A theory is not the same as a hypothesis. A theory provides an explanatory framework for some observation, and from the assumptions of the explanation follows a number of possible hypotheses that can be tested in order to provide support for, or challenge, the theory.
A theory can be normative (or prescriptive), meaning a postulation about what ought to be. It provides "goals, norms, and standards". A theory can be a body of knowledge, which may or may not be associated with particular explanatory models. To theorize is to develop this body of knowledge.
As already in Aristotle's definitions, theory is very often contrasted to "practice" (from Greek praxis, πρᾶξις) a Greek term for "doing", which is opposed to theory because pure theory involves no doing apart from itself. A classical example of the distinction between "theoretical" and "practical" uses the discipline of medicine: medical theory involves trying to understand the causes and nature of health and sickness, while the practical side of medicine is trying to make people healthy. These two things are related but can be independent, because it is possible to research health and sickness without curing specific patients, and it is possible to cure a patient without knowing how the cure worked.

Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. Each observation measures one or more properties (such as weight, location, color) of observable bodies distinguished as independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly stratified sampling. Results from probability theory and statistical theory are employed to guide practice. In business and medical research, sampling is widely used for gathering information about a population.
The sampling process comprises several stages:

Reliability theory describes the probability of a system completing its expected function during an interval of time. It is the basis of reliability engineering, which is an area of study focused on optimizing the reliability, or probability of successful functioning, of systems, such as airplanes, linear accelerators, and any other product. It developed apart from the mainstream of probability and statistics. It was originally a tool to help nineteenth century maritime insurance and life insurance companies compute fair-value rates to charge their customers. Even today, the terms "failure rate" and "hazard rate" are often used interchangeably.
The failure of mechanical devices such as ships, trains, and cars, is similar in many ways to the life or death of biological organisms. Statistical models appropriate for any of these topics are generically called "time-to-event" models. Death or failure is called an "event", and the goal is to project or forecast the rate of events for a given population or the probability of an event for an individual.
When reliability is considered from the perspective of the consumer of a technology or service, actual reliability measures may differ dramatically from perceived reliability. One bad experience can be magnified in the mind of the customer, inflating the perceived unreliability of the product. One plane crash where hundreds of passengers die will immediately instill fear in a large percentage of the flying consumer population, regardless of actual reliability data about the safety of air travel.
Reliability period of any object is measured within the durability period of that object.

We only see responses to the sample of items on the test So, reliability is the proportion of variance in the “universe” explained by the test variance ,Domain Sampling Theory A universe is made up of a (possibly infinitely) large number of items

Is knowledge a matter of being causally connected to the world in the right way? In this Wireless Philosophy video, Jennifer Nagel (University of Toronto) examines the causal theory of knowledge proposed by Alvin Goldman in 1967, and then discusses the problems with the causal theory that led Goldman to formulate his influential reliabilist theory of knowledge.

Reliability theory describes the probability of a system completing its expected function during an interval of time. It is the basis of reliability engineering, which is an area of study focused on optimizing the reliability, or probability of successful functioning, of systems, such as airplanes, linear accelerators, and any other product. It developed apart from the mainstream of probability and statistics. It was originally a tool to help nineteenth century maritime insurance and life insurance companies compute fair-value rates to charge their customers. Even today, the terms "failure rate" and "hazard rate" are often used interchangeably.
The failure of mechanical devices such as ships, trains, and cars, is similar in many ways to the life or death of biological organisms. Statistical models appropriate for any of these topics are generically called "time-to-event" models. Death or failure is called an "event", and the goal is to project or forecast the rate of events for a given population or the probability of an event for an individual.
When reliability is considered from the perspective of the consumer of a technology or service, actual reliability measures may differ dramatically from perceived reliability. One bad experience can be magnified in the mind of the customer, inflating the perceived unreliability of the product. One plane crash where hundreds of passengers die will immediately instill fear in a large percentage of the flying consumer population, regardless of actual reliability data about the safety of air travel.
Reliability period of any object is measured within the durability period of that object.
