Types of Validityand Reliability

1. Face Validity-ascertains that the measure appears to be assessing intended construct under study.www.uni.edu/chfasoa/reliabilityandvalidity

2. Construct Validity-used to ensure that the measure is actually measure what is intended to measure.www.uni.edu/chfasoa/reliabilityandvalidity

3. Criterion-Related Validity-used to predict future or current performance.www.uni.edu/chfasoa/reliabilityandvalidity

4. Formative Validity-It is used to assess how well a measure is able to provide information for improvement. www.uni.edu/chfasoa/reliabilityandvalidity

5. Sampling Validity-ensures that the measure covers the broad range of areas within concept study. www.uni.edu/chfasoa/reliabilityandvalidity

6. Test-Retest Reliability-is a measure of reliability obtained by administering the same test twice over a period of time.www.uni.edu/chfaso/reliabilityandvalidity

7. Parallel Forms Reliability-is a measure of reliability obtained by administering different versions of an assessment tool.www.uni.edu/chfasoa/reliabilityandvalidity

8. Internal Consistency Reliability-is a measure of reliability used to evaluate the degree to which different test items that probe the same construct produce similar results.www.uni.edu/chfaso/reliabilityandvalidity

9. Average inter-item correlation-it is obtained by taking all of the items on test that probe the same construct.www.uni.edu/chfasoa/reliabilityandvalidity

10. Split-half Reliability-the process of obtaining split half reliability is begun by splitting in half all items of a test that are intended to probe the same area of knowledge.www.uni.edu/chfaso/reliabilityandvalidity

11. Inter-rater reliability-measure of reliability used to assess the degree to which different judges or raters agree in their assessment decision.www.uni.edu/chfaso/reliabilityandvalidity
