Learners who did the work, in their own words
About the free library and the teaching behind the credential.
The best free R stats site I've found. Clear explanations, live examples, and zero clutter. Absolute gold for learners.
This site helped me pass my technical interview. Practical R examples gave me the confidence to use statistics at work.
Every tutorial includes reproducible code and real datasets. r-statistics taught me regression better than my grad course.
Questions, answered
What is free, and what is Pro?
The R Foundations track is free in full, every lesson, along with the first section of Data Analyst and of all four specializations, the whole tutorial library and every tool. You can even earn the R Fundamentals certificate at no cost. Pro unlocks the rest of Data Analyst and the four specializations, the graded practice inside them, and the career certificates.
What is the difference between Single Track and All-Access?
Single Track unlocks the shared core plus one specialization of your choice, with grading, and the certificates for both. All-Access unlocks all four specializations and every certificate, for just $64 more a year. Most people start with All-Access to keep their options open.
Can I upgrade from Single Track to All-Access later?
Anytime, and you only pay the difference for the remainder of your term. Your progress, XP, and any certificate you have already earned carry over untouched.
Can I try before I pay?
Yes. Most of the site is free: every tutorial, the first lessons of every course, and all the tools. When you do upgrade, every paid plan carries a 14-day money-back guarantee: if Pro is not for you, email us within 14 days of your first charge for a full refund, no questions asked.
What happens to my work if I cancel?
Your exercises, certificates, and saved posts stay forever. You simply lose access to the Pro sections until you resubscribe.
