The question analysis feature is a premium feature on BrainCert that has been designed to help instructors measure the overall performance & quality of Assessments. The system will automatically generate a report & give a recommendation on whether or not the questions (Multiple choice questions & True or False) in an assessment needs a review based on calculations that measure the Difficulty Index and Discrimination Index.
As the name suggest, Difficulty index is used to identify the difficulty level of questions. The purpose of finding the DI is to decide whether we need to retain the question or modify or remove it for the next test in the same subject.
Discrimination Index is used to identify whether the question helps us to find the low and high performers and it decides whether the question is good at telling who is good performers or bad performers.
