1. Reliability: Does the test yield the same or similar score rankings (all other factors being equal) consistently
2. You look at the operationalization and see whether "on its face" it seems like a good translation of the construct.
3. To show the discriminant validity of a test of arithmetic skills, we might correlate the scores on our test with scores on tests that of verbal ability, where low correlations would be evidence of discriminant validity.
4. Face validity
5. Discriminant validity
6. Content validity
7. This approach assumes that you have a good detailed description of the content domain, something that's not always true
8. Accuracy: Does the test score fairly closely approximate an individual's true level ability, skill, or aptitude?
9. Criterion-Related Validity
10. We assess the operationalization's ability to distinguish between groups that it should theoretically be able to distinguish between.
11. To show the convergent validity of a test of arithmetic skills, we might correlate the scores on our test with scores on other tests that purport to measure basic math ability, where high correlations would be evidence of convergent validity.New node
12. We assess the operationalization's ability to predict something it should theoretically be able to predict.
