2. test-refer or stability -test-reset is a method of estimating relibility that is exactly what its name implies the test is given twice and correlation between the first set of scores and the second set of scores is determined.
3. Content validity evidence
4. Criterion-related Validity evidence
4.1. deals with measures that can be administered at the same time as the measure to be validated
5. Concurrent criterion-re d
5.1. Concurrent criterion-related validity evidence - deal with measures that can be administered at the same time as the measure to be validated
6. used for taking tests that correlate
6.1. Predictive validity evidence
7. construct validity evidence
8. A test has construct validity evidence if its relationship to other information corresponds well some theory.
9. Reliability refer to the consistency with which it yields the same rank for individuals who take the test more than once
9.1. New node
10. alternate forms or equivalence -is used to obtain an estimate of the reliability of the scores from the test
11. Internal consistency -determining a test internal consistency called split haves involves splitting the test into two equivalent halves and determining the correlation between them
11.1. split-half methods - to find the split-half or odd-even reliability each item is assigned to one half or the other
