In the case of reliability estimates, correlations are calculated from the two sets of scores obtained from inter-rater, test-retest or split-half comparisons.

On this basis, it may be assumed that reliability estimates ought to exceed 0.7 if a test is to be regarded as providing 'reliable' scores.

Therefore, FMECA should be used in conjunction with other analytical tools when developing reliability estimates.

However, because the uncertainties in the reliability estimates are in most cases very large, it is likely to dominate the availability (prediction uncertainty) problem, even while maintainability levels are very high.

Measurement error can result from a variety of factors, including true variance not captured by a particular measurement strategy, which may complicate the interpretation of temporal reliability estimates.

First, if the effects of storage time on the analytes were known, we could have taken into account the contributions of this source of variance to our temporal reliability estimates and distinguished its impact from that due to assay reliability.

This halves reliability estimate is then stepped up to the full test length using the Spearman-Brown prediction formula.

Internal consistency, a reliability estimate focusing on how highly test items correlate to each other, is often quite low for TAT scoring systems.

Finally, the mean and median reliability estimates of the BAI tend to be lower when given to a nonpsychiatric population, such as college students, than when given to a psychiatric population.

A wealth of research exists on the PAQ; it has yielded reasonably good reliability estimates and has been linked to several assessment tools" (http://www.job-analysis.net/G012.htm).
