What are two key approaches used to evaluate the overall test or form in Item Response Theory?
- Item difficulty and item discrimination
- Maximum likelihood estimation and Bayesian methods
- Conditional standard error of measurement and test information function (correct)
- Computerized adaptive tests and linear on the fly testing
If the test information function is higher, what does it indicate about the test?
If the test information function is higher, what does it indicate about the test?
- Developing computerized adaptive tests
- Scoring examinees with Bayesian methods
- Having poorly calibrated items
- Providing more measurement information about examinees (correct)
What does a relatively low test information function in a range of examinee ability imply?
What does a relatively low test information function in a range of examinee ability imply?
- Examinees in that range have high scores
- The exam is well-balanced
- The exam has a high level of security
- Those examinees in that range are not being measured accurately (correct)
