Document Summary

Reliability: consistency of a research study or measuring test. Test- retest: same results using the same diagnostic tool, after different periods of time. Refers to the degree to which test results are consistent over time. In order to measure test-retest reliability, we must rst give the same test to the same individuals on two occasions and correlate the scores. Inter-rater: this refers to the degree to which different raters give consistent estimates of the same behaviour. Note, it can also be called inter-observer reliability when referring to observational research. Validity: refers to a test"s ability to measure what it is supposed to measure. Statistical deviation de nition: deviance is related to statistical average- statistically common behaviour is normal and anything that deviated from the norm is abnormal, eg. !q an iq of 150 deviates from norm of 100; it is statistically rare but considered desirable;
