Two of the most important concepts in research methods are reliability and validity. These determine the quality of a study and whether its findings can be trusted.
Reliability refers to the consistency of a measurement or finding. A reliable study produces the same results when repeated under the same conditions. If a study is not reliable, its findings cannot be trusted.
| Type | Description | How to Assess |
|---|---|---|
| Test-retest reliability | The same test produces consistent results when given to the same people on different occasions | Give the test twice to the same participants and compare results |
| Inter-rater reliability | Different observers or raters produce consistent results when measuring the same behaviour | Two or more observers independently record behaviour and their records are compared |
