PSYC31H3 Chapter Notes - Chapter 7: Criterion Validity, Standard Score, Content Validity
Document Summary
Step 1: begins with a domain (type of behaviour that the researcher desires to sample) Step 2: generation of test items to measure the concept. Step 3: test needs to be given to multiple individuals: test items will be added/deleted depending on usefulness. Step 5: standardization: uniformity of procedure in administering and scoring a test. Reliability: extent to which a test is repeatable and yields consistent scores: test reliability: consistency of score obtained by the same individual when retested with the identical test or an equivalent form of the test. Validity: how valid a test is depends on what the test measures and how well it measures that subject. Convergent validation: a test must demonstrate that the test correlates highly with other variables with which it theoretically should. Discriminant validation: test should not correlate with variable with which it should differ.
