Validity and Reilability

1. Predictive Validity Evidence

1.1. "How well the test predicts some future behavior of the examinees (good for aptitude tests)" (Kubiszyn, 2013, p. 328)

2. Construct Validity Evidence

2.1. "A test has construct validity evidence if its relationship to other information corresponds well with some theory" (Kubiszyn, 2013, p. 329)

3. Reilability

3.1. "The reliability of a test refers to the consistency with which it yields the same rank for individuals who take the test more than once.' (Kubiszyn, 2013, p. 338)

4. Test-Retest Reliablity

4.1. "Test given twice and the correlation between the first set of scores and the second set of scores is determined" (Kubiszyn, 2013, p. 338)

5. Alternate form Reliability

5.1. "2 forms equivalent forms f a test are administered to a group of students and the correlation between the two sets of scores is determined" (Kubiszyn, 2013, p. 340)

6. Internal Consistency Reliability

6.1. "Test items ought to be correlated with each other and the test ought to be internally consistent. if this is the case, the reliability of the scores for the test can be estimated by the internal consistency method" (Kubiszyn, 2013, p. 340)

8. Content Validity Evidence

8.1. "is established by inspecting test questions to see whether they correspond to what the user decides should be covered on the test (Kubiszyn, 2013 p.327)"

9. Criterion - Related Validity Evidence

9.1. "Scores from a test are correlated with an eternal criterion" (Kubiszyn, 2013, p. 327)

10. Concurrent Criterion - Related Validity

10.1. "measures that can be administered at the same time as the measure to be validated" (Kubiszyn, 2013, p. 328)
