Document Summary

Knowledge generation and mobilization in psychology (part 2) 1: 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. It can be replicated: concern to reduce bias. 4: shared with others (ideally made openly accessible) Objective: 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. E. g. number of drinks consumed: in psych, often measure behaviour. Reliable: when a measure provides consistent and stable answers across multiple observations and points in time: reliability is often assessed in terms of , test re-test reliability. E. g. your score on a b test of social anxiety today and on the same test tomorrow, should be quite similar. A measure with high internal consistency the answers should converge on the variable you are trying to measure.
