It presents the similarities and differences in the approach to this problem for the one-parameter Rasch model and the two-parameter Birnbaum model. All kinds of relationships are presented in graphs. Additionally, special attention is paid to the interpretation of these graphs and the results.}, title={The item information function in one and two-parameter logistic models – a comparison and use in the analysis of the results of school tests}, type={artykuł}, keywords={item information function, Rasch Model, Birnbaum Model}, }
