Question statistics​

eXamc question statistics

Question-level views can help identify unusual response patterns.

The indicators are interpreted as follows:

  • Upper: responses from the best-performing 27% of students;
  • Lower: responses from the lowest-performing 27% of students;
  • Discriminatory: difference between Upper and Lower responses. A negative value should prompt a review of the question wording and answer key.

Also compare the list of absent students with the attendance information collected during the exam.
