    Glossary Reliability Coefficient

    measure of consistency in test results over time

    The reliability coefficient is a measure used in statistics and psychology to assess the consistency or stability of a test or measurement over time. For example, if a hair growth study uses a specific method to measure hair density, the reliability coefficient would indicate how consistently that method produces the same results under the same conditions. A high reliability coefficient means the measurement is dependable and can be trusted to give similar results in repeated trials.
