Document Summary

Reliability: examination of the consistency (or inconsistency) of test scores. Validity: examination of the inferences and conclusions drawn from test scores. Reliability: estimates how much error is involved in their score (is the observed cognitive ability score a good representation of their true score) Validity: estimates whether or not our measure actually reflects cognitive ability and/or whether or not choosing someone based on their score from this measure will result in a specific outcome (better performance) Examination of whether or not a psychological test actually measures what it says it does. Identify the content domain for a desired population. No exact method: describe the content domain (see above, determine the area(s) of the domain measured by each item, compare the structure of the test with the domain. Examination of the outcomes resulting from decisions based on test scores. Total set of behaviours that could be used to measure a specific attribute or characteristic.
