Diagram illustrating how the addition of different components leads to changes in estimated parameter values. Panels show best-fit parameters averaged across all questions, with the right-hand panel re-scaled for clarity. For each format, the predicted proportion of student answers is first shown under a simplified model in which all students only use informed reasoning based on the attractiveness of the response options. Subsequent columns include the stated model component in addition to parameters to the left
