Alternative Forms Reliability
Alternative forms reliability is a type of reliability assessment that compares the scores of individuals on two different versions of the same test. It measures the consistency of a test over multiple administrations and helps to determine whether the test is providing consistent results.
Procedure:
1. Create two equivalent versions (Forms A and B) of the test.
2. Administer Form A to a group of individuals.
3. Administer Form B to the same group of individuals at a later time.
4. Calculate the correlation between the scores on Form A and Form B.
Interpretation:
- High Correlation (0.80 or above): Indicates that the test is reliable and provides consistent results across different versions.
- Moderate Correlation (0.60-0.79): Suggests that the test has moderate reliability but may need some improvements.
- Low Correlation (below 0.60): Indicates that the test lacks reliability and may not provide consistent results.
Advantages of Alternative Forms Reliability:
- Assesses the consistency of the test over time.
- Helps to identify items or sections that are not functioning well.
- Can be used to create a composite score by combining the scores from multiple test versions.
Limitations of Alternative Forms Reliability:
- Requires the creation of multiple test versions, which can be time-consuming and costly.
- May not be feasible for tests that are administered over a short period.
- Can be affected by practice effects or other factors that influence the scores on the different forms.
Applications of Alternative Forms Reliability:
- Assessing the reliability of educational and psychological tests
- Evaluating the consistency of diagnostic tools
- Validating new test versions
- Identifying areas for test improvement
