Question Difficulty Index helps to assess the difficulty level of each question in comparison to the difficulty level that was assigned while creating the question. When any question gets created, a difficulty level is assigned to it. However, as the question gets attempted by candidates, the actual difficulty level may change. For e.g. while creating a question the difficulty level assigned might be Easy, whereas the majority of the candidates may not find it that easy to solve the question. In this case, the Assigned Difficulty Index is Easy, whereas the Difficulty Index calculated will be medium.
Difficulty Index is calculated for questions with 100+ attempts
