Comparing Item Characteristic Curves.
Rosenbaum, Paul R.
Psychometrika, v52 n2 p217-23 Jun 1987
This paper develops and applies three nonparametric comparisons of the shapes of two item characteristic surfaces: (1) proportional latent odds; (2) uniform relative difficulty; and (3) item sensitivity. A method is presented for comparing the relative shapes of two item characteristic curves in two examinee populations who were administered an admissions test. (Author/GDC)
