What is differential item functioning (DIF) analysis primarily used to detect?
Answer: Items that perform differently for subgroups with equal ability levels
DIF analysis identifies items where examinees of equal ability but different demographic subgroups (e.g., gender, ethnicity) have systematically different probabilities of answering correctly, flagging potential bias.
In item response theory (IRT), what does the 'b' parameter represent?
Answer: Item difficulty or location on the ability scale
In IRT, the b parameter (difficulty or location parameter) indicates the point on the ability scale where an examinee has a 50% probability of answering the item correctly.
Which item bank management practice helps maintain test security when many test forms are needed over time?
Answer: Tracking item exposure rates and retiring overexposed items
Monitoring and controlling item exposure rates prevents frequently seen items from becoming known to future examinees, protecting the integrity and validity of the test.
What is the purpose of anchor items (common items) when equating scores across test forms?
Answer: To provide a set of identical items across forms that link the forms to a common scale
Anchor items appear on multiple test forms and allow scores to be placed on a common scale, compensating for differences in form difficulty during equating.
Which index is commonly used in classical test theory to assess how well an item separates higher-ability examinees from lower-ability examinees?
Answer: Point-biserial correlation (item-total correlation)
The point-biserial correlation measures the relationship between performance on a single item and total test score, indicating how well the item discriminates between high and low performers.
When reviewing items for sensitivity concerns, what is the primary goal?
Answer: To identify and remove content that may offend, stereotype, or disadvantage particular groups
Sensitivity reviews identify language, images, or scenarios that could be offensive, stereotyping, or culturally biased in ways that unfairly disadvantage certain groups of examinees.
What is a 'key' in the context of multiple-choice item development?
Answer: The correct answer to a multiple-choice item
In testing terminology, the 'key' refers specifically to the correct answer option among the choices provided in a multiple-choice item.
