Document Summary
Self-report (tell me about yourself) e. g. big 5, interview, beck depression. Informant"s report (ask someone who knows you) e. g. big 5, Life outcomes (what has happened in your life) Behavioral observations (lets see what you do) - naturalistic and performance measures (e. g. iat, rorschach) includes lab studies. A reliable measure is a consistent measure. Definition: the degree to which a test produces the same results when given under the same conditions. Research is all about understanding what accounts for (explains) why the numbers are not all the same. States versus traits - there is an important distinction. The extent to which a test measures what it intends to measure. The extent to which a concept, conclusion, or measurement corresponds accurately to the real world. A test can be highly reliable and not at all valid - your astrological sign. A test cannot be valid if it is not reliable e. g. myers-briggs type indicator (mbt)
