Reliability Coefficient

The reliability coefficient measures how consistently a test or assessment produces the same results under consistent conditions. Think of it as a score that indicates the dependability of the test: a high reliability coefficient means the test is stable and trustworthy, giving similar outcomes if repeated. For example, if a personality quiz has a high reliability coefficient, it suggests the results are consistent and not significantly influenced by random factors or measurement errors. This helps ensure that the test accurately reflects what it's intended to measure, providing confidence in its results.
