StepStat

StepStat provides free, in-browser statistics calculators that show formulas and step-by-step solutions, useful for students and researchers who want transparent worked examples.

Quick Verdict

StepStat is a small independent site that offers free, step-by-step statistics calculators which display formulas, intermediate steps, and final results. It is worth checking if you need a readable walkthrough for common statistics tasks (mean, median, mode, variance, standard deviation, z-scores, confidence intervals) rather than just a numeric answer.

Key Features

• A collection of common statistics calculators (examples listed by the website include variance, z-scores, mean, median, mode, standard deviation, average, and confidence intervals).
• Each calculator shows the formula and intermediate steps in addition to the final result, which helps with learning and verification.
• Calculations run client-side in your browser, so the site describes that it does not upload or store the numbers you enter into a calculator.
• The calculators are offered free to users.
• The website describes a privacy policy and notes that it may use privacy-conscious analytics and collect technical/analytics data.

Who this is for

Best-fit users: students, researchers, and anyone who wants transparent, worked examples for basic statistical calculations or quick verification of hand calculations. The site appears to be most useful for learning, homework checks, or quick ad-hoc computations.

Limitation / thing to verify: the website does not clearly state a complete inventory of all supported calculators, details about accuracy checks or formula sources, or whether results are suitable for high-stakes decisions. Verify on the official website whether a needed calculator exists, how formulas are sourced or validated, and what analytics the site collects before entering sensitive data.
