Detailed explanation-1: -Reliability refers to how dependably or consistently a test measures a characteristic. If a person takes the test again, will he or she get a similar test score, or a much different score? A test that yields similar scores for a person who repeats the test is said to measure a characteristic reliably.
Detailed explanation-2: -Reliability refers to the consistency of a measure. 1 A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.
Detailed explanation-3: -Reliability is another term for consistency. If one person takes the samepersonality test several times and always receives the same results, the test isreliable. A test is valid if it measures what it is supposed to measure.
Detailed explanation-4: -Reliability is the degree to which an assessment tool produces stable and consistent results. Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals.
Detailed explanation-5: -Tests. A consistent test is one for which the power of the test for a fixed untrue hypothesis increases to one as the number of data items increases.
