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).
