Types of Validity and Reliability by Mind Map: Types of Validity and Reliability

1. Types of Validity

1.1. Content Validity Evidence

1.1.1. See if test questions correspond

1.2. Criterion Related Validity Evidence

1.2.1. Are scores from a test correlated with an external criterion

1.3. Concurrent Criterion Related Validity Evidence

1.3.1. Measures that can be administered at the same time

1.4. Predictive Validity Evidence

1.4.1. How well test predicts

1.5. Construct Validity Evidence

1.5.1. Relationship correlates well with some theories

2. Methods of Estimating Reliabiltiy

2.1. Test-Retest or Stability

2.1.1. Methods of estimating reliability

2.2. Alternate Forms of Equivalence

2.2.1. Used to obtain an estimate of the reliability of scores

2.3. Internal Consistency

2.3.1. Designed to measure a single basic concept

2.4. Split-Half Methods

2.4.1. Odd-Even Reliability

2.5. Kuder-Richardson Methods

2.5.1. Represents a single, fairly consistent measure of a concept

3. Reliability

3.1. The Consistency with which it yields the same rank for individuals who take the test more than once

3.2. Stability of a test score over repeated administrators

3.3. Will yield stable scores

4. Validity

4.1. Does it measure what it is supposed to measure

4.2. Is the test valid for the intended purpose

4.3. Does the test do the job it was supposed to do
