Published banks of multiple-choice questions are ubiquitous, the questions in those banks often being classified into levels of difficulty. The specific level of difficulty into which a question is classified might or should be a function of the question’s substance. Possibly, though, insubstantive aspects of the question, such as the incidence of incorrect answers that are readily dismissed, also affect the difficulty level into which a question is classified. The present research investigates the relationship between classified question difficulty and the incidence of implausible incorrect answer options.
