WebReliability (statistics) In statistics, reliability is the consistency of a set of measurements or measuring instrument, often used to describe a test.This can either be whether the measurements of the same instrument give or are likely to give the same measurement (test-retest), or in the case of more subjective instruments, such as personality or trait … WebReliability Theory Sec. 13.4. We explain how the basic reliability functions can be estimated from failure data in Sec. 13.5. In the next unit, we shall discuss reliability evaluation of simple systems.
