Document Summary
Establish relationship: data collection stage, what to attend to. Reliability: test-restest (same test twice, equivalent form (2 diferent tests measuring same thing) *errors in reliability: subjects inluenced by external events, tester being biased, situation and environment: internal consistency: tested with split half test. Validity: face validity (does it look like what it measures?, the value and true validity or predictive validity ex: iq. *can predict outcomes with great predictive validity and can be systematically measured. *iq level afected by low ses and mother marital status. *rost tests at diferent colleges including harvard and corporate managers, prefrontal lobe factors seem to be more predictive of performance than iq. Objective test projective test job= task job= report stimulus= structured stimulus= luid instructions= speciic instructions= indeinite answer= yes/no answer= anything rationale= comparison rationale= projective hypothesis scoring= speciic scoring= inter-test. *cannot get better test validity than what you"re trying to classify.
