Test-retest reliability

Explanation:

Test-retest reliability has happened in statistical analysis. Test-retest reliability is of reliability. It is the external reliability. It is a statistical measurement tool to measure that the test is valid or not. It is about to conduct a test first time on a population and then again apply to the population. If the score of the first trial and the second trial are the same, the test will be valid. It indicates that the test is replicate and can be used more than one time at a specific period. The test-retest reliability indicates that the test has good validity. It is conducted two times T1 and T2 and the score will be the same. Linear correlation is used to measure the test-retest reliability of a test
