What to contact us about

• A wrong answer or a wrong page. Tell us the page, the numbers you entered, and what you expected — calculation corrections are our top priority and are usually fixed the same day.
• A calculator or guide you wish existed. The cluster grows by demand; if a descriptive-statistics tool is missing, say the word.
• Teaching use. Teachers and tutors are welcome to link to any calculator or guide — no permission needed for links.

Please do not send personal data sets you would not paste into a web page. (For the record, the calculators themselves never transmit your numbers anywhere — calculations happen in your browser.) We read everything and reply to most messages within a few working days.
