Validity & Reliability
by Tanequia C
1. Reliability
1.1. Test-retest or stability
1.1.1. intervals between test must be taken into consideration
1.2. Alternate forms or equivalence
1.2.1. maintaining test security (same test, different order/wording)
1.3. Internal consistency
1.3.1. Split-half methods
1.3.1.1. most frequently used method of reliability
1.3.2. Kuder-Richardson methods
1.3.2.1. measures the commonality between test
2. Organization
2.1. Prioritize each task based on levels of criticalness
3. Validity
3.1. Content Validity
3.1.1. minimum requirement for test
3.2. Criterion-Related Validity
3.2.1. Concurrent
3.2.1.1. administering both test (new & established) then find correlation between the two
3.2.2. Predictive
3.2.2.1. more useful w/ aptitude test; (beta test) determine how well testers will do in the future
3.3. Construct Validity
3.3.1. Information corresponds well w/theory
