Document Summary

Score participants would obtain if measurement was perfect (able to measure w/o error) Test-retest reliability : measure same person at two different times, correlation coefficient of . 80 is lowest acceptable. Alternate forms reliability: administering two different forms of the same test. Inter-rate reliability : two different rater/experimenters run the same experiment to makesure both receive the same or similar scores/rating: list & define 3 different types of internal consistency measures. Internal, external, content, construct, temporal, face, and convergent (criterion) 1. internal validity- degree to which mathematical relationships we observe b/w participants" scores actually and only reflect relationship b/w variables of interest no confounding variables. 3. content validity: degree to which measurement actually relfects variable/behavior of interest. 4. construct validity: extent to which measurement reflects hypothetical construct of interest. 5. temporal validity: measurements obtained from a particular test are stable across time. 6. face validity: test is measuring what it seems to measure.
