Validity & Reliability

1. Validity

1.1. Content Validity

1.1.1. minimum requirement for test

1.2. Criterion-Related Validity

1.2.1. Concurrent

1.2.1.1. administering both test (new & established) then find correlation between the two

1.2.2. Predictive

1.2.2.1. more useful w/ aptitude test; (beta test) determine how well testers will do in the future

1.3. Construct Validity

1.3.1. Information corresponds well w/theory

2. Reliability

2.1. Test-retest or stability

2.1.1. intervals between test must be taken into consideration

2.2. Alternate forms or equivalence

2.2.1. maintaining test security (same test, different order/wording)

2.3. Internal consistency

2.3.1. Split-half methods

2.3.1.1. most frequently used method of reliability

2.3.2. Kuder-Richardson methods

2.3.2.1. measures the commonality between test

3. Hypothesis

3.1. Theory

3.2. Solution

4. Organization

4.1. Prioritize each task based on levels of criticalness
