SEM quantifies the degree of uncertainty in an individual's observed score, typically displayed as a confidence interval around that score.

Question 4

In a 3-parameter logistic (3PL) IRT model, what does the 'c' parameter represent?

Accepted Answer

Lower asymptote / pseudo-guessing

Answer

The 'c' parameter in 3PL IRT represents the lower asymptote, modeling the probability that a very low-ability examinee still answers the item correctly by guessing.

Criterion-referenced interpretation judges whether a candidate meets a predetermined performance standard, independent of how others performed.
