Document Summary

Based on measurements that are objective, valid and reliable. Generalizable (or at least the generalizability across groups of people has been considered, e. g. , culture, gender) Shared with others (ideally made openly accessible) The measure of a variable that, within a margin of error, is consistent across instruments and observers. Variables refers to the object, concept, event or behaviour being measured. In psychology often measure behaviour: self-report, third party observation, physiological measure. When a measure provides consistent and stable answers across multiple observations and points in time. In psychology reliability is often assessed in terms of: 1. E. g. , your score on a test of social anxiety today and on the same test tomorrow should be very similar: 2. A measure with high internal consistency the answers should converge on the variable you are trying to measure. E. g. , below are two items from a measure of social anxiety. Your answers to these two test items should be related.
