FAQ
What data do I need to get started?
Just upload your quiz response data as a CSV or JSON file. The app handles the rest — no coding or statistics knowledge required.
How does the difficulty calibration work?
We calculate the p-value (proportion of correct answers) and point-biserial discrimination index for each question, then flag items outside optimal ranges.
