Document Summary
Alternate form reliability the correlation between 2 forms of a test with different items that are measuring the same attribute. Concurrent validity the extent to which test results are correlated with a specified criterion in the present. Content validity type of test validity that addresses the degree to which the test adequately samples the relevant material. Convergent validity validity supported by a substantial correlation of conceptually similar measures. Criterion validity extent to which a measure correlates with one or more criterion variables. Cronbach"s alpha measure of internal consistency reliability. Discriminant validity validity supported by a lack of correlation between conceptually unrelated measures. External validity degree of generalizability to particular populations, settings, treatment variables and measurement variables. Face validity extent to which a test seems on its surface to be measuring something it purports to measure. Internal consistency reliability reliability based on the intercorrelation among components of a test, such as sub-tests or all individual item tests.
