1. Construct validity is the umbrella under which all of the other sub-types of validity fall (Cohen & Swerdlik, 2010). Construct validity is appropriate to use in cases where a test is trying to measure some underlying construct, such as intelligence or anxiety. I suppose this measure of validity might not be appropriate in situations where there is not one clear construct that is being measured, such as generalized achievement tests.

10. The strength of this measurement of reliability are in tests that, “…employ outcome measures such as reaction time or perceptual judgment” (Cohen & Swerdlik, 2010, p. 143). This is because these types of psychometric traits do not vary greatly over time and are not sensitive to many types of intervening variable.
11. The weakness of test/retest reliability is, of course, that the underlying constructs being tested can change over time, and therefore lower the test/retest reliability due to true variance rather than error variance. In this case, the overall reliability of a test might be seen as lower even though the actual measurement of the construct is stable (it is just that the construct itself varies).
