12 Questions
What are two key approaches used to evaluate the overall test or form in Item Response Theory?
Conditional standard error of measurement and test information function
If the test information function is higher, what does it indicate about the test?
Providing more measurement information about examinees
What does a relatively low test information function in a range of examinee ability imply?
Those examinees in that range are not being measured accurately
How is the conditional standard error of measurement related to the test information function?
It is the inverse of the TIF
What is a 95% confidence interval for a person's score calculated using the standard error of measurement?
$\pm 1.96$ times the SEM
In what context would data forensics using Item Response Theory be valuable?
To find cheaters or issues with examinee responses
What is the main focus of Item Response Theory (IRT)?
Modeling responses to test items
Which of the following is a technique associated with Item Response Theory (IRT)?

What are the two primary approaches in analyzing test data within psychometric theory?
Classical Test Theory (CTT) and Item Response Theory (IRT)
Explore the fundamental psychometric framework of Item Response Theory (IRT) which models responses to test items and latent traits. Learn about differential item functioning, computerized adaptive testing, and item analysis within IRT. Understand the theoretical and computational development of IRT since the 1950s.
