Final Flashcards
Refers to the consistency of a testing method
Reliability
Refers to the method measure lathe ability or trait it is intended to measure
Validity
Observed score -true score
Error
The extent to which scores from administrations of the same test are correlated. A test is considered to have good test retest reliability if the correlation is above .70
Test-retest reliability
Because tests with high test-retest reliability yield scores that remain stable over time, they are said to have…..
Temporal stability
The extent to which scores from two forms of a test are correlated
Alternate forms reliability
The order in which examinees take each form is typically counterbalanced
Counterbalancing
Because tests with high alternate forms reliability yield scores that are stable across forms, they are said to have…..
Form stability
The extent to which similar test items are answered in similar ways.
Internal consistency
The extent to which items measure the same thing
Item homogeneity
The extent to which a predictor test score is correlated with a criterion for job performance
Criterion validity
A selection test is given to current employees for which job performance is already known
Concurrent validity design
A selection test is given to a group of job applicants who are then evaluated on a criterion at a later point
Predictive validity design
The extent to which a test actually measures the construct that it purports to measure
Construct validity
The extent to which two tests measuring the same construct are correlated should be correlated
Convergent validity
