Test Reliability

Test reliability refers to the consistency of a test in measuring what it is designed to measure. For example, if you take a general knowledge quiz multiple times and consistently score around the same range, the test is considered reliable. It means that the results are stable and can be trusted over repeated uses. High reliability ensures that the test is accurate and not heavily influenced by random factors like guessing or temporary knowledge lapses. In essence, a reliable test provides dependable results that reflect an individual's true knowledge level.
