Various Types of Validity and Reliability By: L. Applewhite

1. Reliability

1.1. Test Retest

1.1.1. The same test is taken more than once.

1.2. Internal consistency estimates of reliability

1.2.1. Test premediated to assess a particalur concept.

1.2.1.1. Kuder- Richardson methods

1.2.1.2. Split half estimates

1.2.1.3. Odd-even estimates

1.3. Alternate Form estimates of reliablilty

1.3.1. Given two different versions of corresponding test

2. Accuracy

3. Vadility

3.1. Content Validity evidence

3.1.1. examines test questions to distinguish whether they correspond to what should be covered on the test

3.1.1.1. concurrent valdity

3.1.1.2. predictive valdity

3.2. constrict valdity evidence

3.3. Criterion related evidence
