Document Summary
The extent to which measures of the same phenomenon are consistent and repeatable; measures high in reliability contain a minimum of measurement error (g & g, 2013, p. 500) . If a measure is not reliable, it is difficult to know what a score on the measure actually means. Iq test example: reliability is necessary, but not sufficient in order to have a good measure. **just because it is reliable does not mean that it is accurate** Content validity: whether or not the actual content of the items on a test makes sense in terms of the constructs being measured (g & g, 2013, p. 119) . Face validity: not a real type of validity, whether the measure seems valid to those who are taking it (g & g, 2013, p. 119) . Criterion validity: concerns whether the measure(s) can accurately forecast some future behaviour or (b) is meaningfully related to some other measure of behaviour (g &
