Reliability (statistics): Measurement, Estimation & Types

In statistics and psychometrics, reliability is the freedom of a measure from measurement error. In Classical Test Theory, reliability is the proportion of the observed test score variation due to "true" score variation. A measure with high reliability tends to produce similar measurements under consistent conditions:
