Child Psych

Answer: A - A study showing evidence of substantial correlations between two different forms of a test provides evidence of the test’s reliability-how consistent of a measure it is. Validity refers to the degree to which the test is actually measuring what it is supposed to be measuring. A test can still be a reliable measure of whatever it is intended to measure, but not a valid one. In regard to the above example, halo and practice effects are not a factor.
