Validity and Reliability by Mind Map: Validity and Reliability

1. Construct Validity is important in learning and assessment because it correlates the results of the test with what you would expect to know.

2. Internal consistency reliability consist of three main techniques for measuring.

2.1. split halves test for internal consistency reliability is the easiest type, and involves dividing a test into two halves.

2.2. Kuder-Richardson test for internal consistency reliability is a more advanced, and slightly more complex, version of the split halves test

2.3. Cronbach's Alpha test not only averages the correlation between every possible combination of split halves, but it allows multi-level responses

3. Inter-Rater Reliability

3.1. a measure of reliability used to assess the degree to which different judges or raters agree in their assessment decisions. Inter-rater reliability is useful because human observers will not necessarily interpret answers the same way; raters may disagree as to how well certain responses or material demonstrate knowledge of the construct or skill being assessed.

4. Content Validity is important in learning and assessment because it matches the test questions to the instructional objectives.

5. Test-retest reliability is desirable in measures of constructs that are not expected to change over time

5.1. Same people, different times

6. INTERNAL VALIDITY

6.1. Internal validity is a measure which ensures that a researcher's experiment design closely follows the principle of cause and effect.

7. TEST VALIDITY

7.1. Test validity is an indicator of how much meaning can be placed upon a set of test results.

8. Concurrent Criterion-Related Validity is important in learning and assessment because it allows teachers to compare the students performance.

8.1. Criterion Validity assesses whether a test reflects a certain set of abilities.

9. Predictive Validity is important in learning and assessment because it will predict how well test takers will do in the future.
