Validity and Reliability por Mind Map: Validity and Reliability

1. Internal Consistency - If this is the case, the reliability of the scores for the test can be estimated by the internal consistency method.

2. Alternate forms or Equivalence-Both forms are administered to a group of students, and the correlation between the two sets of scores is determined. This estimate eliminates the problems of memory and practice involved in test–retest estimates.

3. Test–retest is a method of estimating reliability that is exactly what its name implies. The test is given twice, and the correlation between the first set of scores and the second set of scores is determined.

4. Constructed Validity Evidence- construct validity evidence if its relationship to other information corresponds well with some theory. A theory is simply a logical explanation or rationale that can account for the interrelationships among a set of variables.

5. Predictive Validity Evidence- how well this test will be predicts the future behaviors of the testers.

6. Concurrent Criterion- Related Validity Evidence is measure that can be administered at the same time as the measure to be validated.

7. Criterion- Related Validity Evidence- score related with external criterion

8. Problems with Content Validity Evidence – difficult are testing personality an aptitude traits. Another problem – tells if test appears valid but does not tell whether test reading level is too high or if question are poorly stated. Test could look valid but measure something unintended Content Validity Evidence is therefore a minimum requirement.

9. Validity Validity is all about evidence for what ever is to be measured.

10. RELIABILITY of a test refers to the consistency with which it yields the same rank for individuals who take the test more than once.

11. Content Validity Evidence –inspecting test question to make sure they correspond to what is on the test.
