Frequently Asked Questions
Can I use the calculators without signing up?
Yes! All calculators are completely free and require no sign-up. You can calculate t-tests, ANOVA, chi-square, correlation, and descriptive statistics instantly.
What does the AI interpretation include?
Our AI analyzes your statistical results and generates: (1) a publication-ready result sentence in APA format, (2) a plain-language interpretation anyone can understand, and (3) important caveats and limitations to consider.
What format is the Word export?
We generate APA 7th edition formatted tables in .docx format. Tables follow APA guidelines: no vertical lines, proper header formatting, italic statistical symbols (M, SD, t, F, p), and Times New Roman 12pt font.
Can I cancel anytime?
Yes. You can cancel your subscription at any time. You'll keep Pro access until the end of your billing period.
Is my data safe?
All calculations run in your browser. Your raw data never leaves your device. For AI interpretation, only the computed statistics (not your raw data) are sent to our server.
Do you offer student discounts?
We're planning student pricing soon. For now, the free AI trial and affordable Pro plan ($5.99/mo) make it accessible for any student.
