The study explored the use of the Item Information Curve (IIC) as a weighting strategy (i.e., Weighted Area Method - WAM) to the area between Item Characteristic Curves (ICC) as a way to identify problematic questions. Through thousands of simulations, the performance of WAM was compared ...

(2) the information function is given as (3)I(θ)=ai2QiPi[(Pi−ci)2(1−ci)2] The standard error of estimation of θ is equal to 1/I(θ). A plot of an information curve and corresponding standard error is displayed in Fig. 2. Unlike the standard error of measurement ...
