WebThe ICC curve is essentially a curve for an item \(j\) that plots the relationship between \(\theta\): ability of examinee; and \(P_j(\theta)\): probability of answering \(j\) correctly. As ability changes, probability of correct response also changes. The ICC shows how it changes. What we want to do next is to draw ICCs for each GRE40 item.

WebOct 4, 2024 · What is IRT ICC? Item Response Function and Item Characteristic Curve (ICC) IRT models predict respondents’ answers to an instrument’s items based on their position on the latent trait continuum and the items’ characteristics, also known as parameters. Item response function characterizes this association. WebI am using the ltm package in R to examine this within a item response theory (irt) paradigm, using a graded response model (grm). For each item, I am given a "discrimination value" that corresponds with the slope of the ICC at each level given the ability level. For my six items, the values are (approximately): 2.1, 1.8, 1.3, 0.8, 2.7, 2.3.
