Questions and Answers / Characteristic Curves by Category
« on: November 19, 2014, 10:39:27 AM »
Hi everyone!
I am working with MC-items and I want to analyse the characteristic curves "by category" to understand my items better. Plotting those curves, concquest (or poltquest) uses the raw data for the curves representing the probability for the distractors. Is there any possibility to get "smoothed" model porbability curves for all categories? Right now, conquest just shows this model probability curve for the right answer.
Thanks for you help!
