Detailed explanation-1: -Test reliablility refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Most simply put, a test is reliable if it is consistent within itself and across time.
Detailed explanation-2: -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-3: -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-4: -Reliability Example: IQ Test An intelligence test, or IQ test (IQ = intelligence quotient), typically has a mean score of 100 and a standard deviation of 15. Therefore, a score of 130 is 2 standard deviations above the mean, which indicates the person receiving that score is above average in intelligence.
Detailed explanation-5: -Formative Assessment is the most powerful type of assessment for improving student understanding and performance.
