Descripción: This audio podcast explains the different ways we may sketch an Item Characteristic Curve (ICC), even using just a pocket calculator and a piece of paper.
In Item Response Theory (IRT), an ICC is the graphical expression of a logistic function (like a 1PL 2PL or 3PL model) and shows the probability of the correct answer (P(Theta)) for every latent trait level (Theta).

This video shows how to work out the proportion and the percentage of agreement between two raters. It also shows how to calculate the proportion and percentage of agreements for a specific cell. Document P08.1, slides 6 and 7.
This podcast explains slide 2 from the document “T13.01. Information functions”. Contents: -Description and interpretation of a graph displaying the ICCs of two items. -Comparison of the two ICCs from the perspective of the item the discrimination.
Each logistic model (1PL, 2PL or 3PL) presents a definite way of Item Characteristic Curve. How to identify which logistic model to apply based on the ICC graphs? This podcast explains how to choose the logistic model based on the ICC graphs on slide 2 in the document T13.01.
T05.1 Slides 2-9. "Situation 1": The definition of the true score, the observed score, and the error of measurement. Why the sum (and the mean) of the errors of measurement is always 0 in situation 1.
