Validity and Reliability by Mind Map: Validity and Reliability

1. Split Half is splitting the test into two equal parts

2. Internal Consistency is used to tell if a test is designed to measure the basic concept

3. Alternate Forms or Equivalence is when two forms of a est is given to the same students. If the test come back with similar scores it is reliable but if they come back way off the test is unreliable.

3.1. Session Rule 1

3.2. Session Rule 2

4. Test-Retest is when the test is given twice to compare scores of the same students. This can tell if the first score was reliable.

4.1. Goal 1

4.2. Goal 2

5. Content Validity Evidence is when the information on a test is inspected to see if he corresponds with the information that was given for the test.

6. Predictive validity evidence tells how well the est predicts future behavior. It allows an educator to see how well the student will do on future test.

7. Concurrent criterion-related validity evidence is giving a new version and an established version and finding the correlation. This is important because it tells if the substance measures up

8. Methods of Reliability

9. Interpreting Reliability Coefficients

9.1. Group variability affects the size of the reliability coefficient

9.2. Scoring reliability limits test score results

9.3. the more items included in a test the higher the reliability will be

9.4. reliability tends to change if the test becomes to easy or hard

10. Content Validity Evidence

11. Criterion-Related Validity Evidence
