For example, if a test is designed to measure a trait (such as introversion ), then each time the test is administered to a subject, the results should be approximately the same. Reliability is a prediction of the performance of a system or product in the future. Alternate Form Reliability.

Terms of Reliability and Validity in Psychology. Reliability in psychological research isn't really that different - it means that your tools for measuring a given variable measure it accurately and consistently. Reliability definition psychology refers to the ability of a research study or test to provide the same results after being performed on more than one occasion. A test is considered reliable if we get the same result repeatedly. i like it. Methods of estimating reliability and validity are usually split up into different types. The extent to which the findings can be repeated. Examples of reliability requirements specifications are as follows: 1. Reproducibility is different to repeatability, where the researchers repeat their experiment to test and verify their results.Reproducibility is tested by a replication study, which must be completely independent and generate identical findings known as commensurate results. Definition Student One: I'm glad that is over. Especially if each judge has a different opinion, bias, et cetera, it may seem at first blush that there is no fair way to evaluate the pieces.

Alternate form reliability occurs when an individual participating in a research or testing scenario is given two different versions of the same test at different times. If you get an identical measurement twice, you can be confident you measured reliably. Or, equivalently, one minus the ratio of the variation of the error score and the variation of the observed score: 1.
