Comparing different item thresholds for Rasch rating scale model / Sholeh Ataei

Measurement issues are old issues in educational testing, and some of them are still unsolved. The Rasch rating scales model is a unidimensional measurement model for analyzing data on human attitudes. This mathematical model describes the two parameters: items and persons as agents of response. Thi...

description Measurement issues are old issues in educational testing, and some of them are still unsolved. The Rasch rating scales model is a unidimensional measurement model for analyzing data on human attitudes.
