Sigma Calculator — 80+ Free Tools

Statistics Calculators

Free statistics calculators for mean, median, standard deviation, probability & distributions — fast, accurate, no sign-up.

Make sense of data with our free statistics calculators — built for students, researchers, analysts, and anyone who needs fast, reliable answers from numbers. From everyday averages like mean, median, and mode to deeper measures like standard deviation, variance, probability, and distributions, these tools handle the heavy lifting so you can focus on insights, not arithmetic.

Statistics powers decisions everywhere: a student analyzing survey results, a marketer measuring campaign performance, a scientist testing a hypothesis, or a sports fan comparing player averages. Manually working through formulas for standard deviation or computing probabilities by hand is slow and error-prone. Our calculators do it instantly — just enter your data set and get clear, precise results in seconds.

This hub covers descriptive statistics (mean, median, mode, range), measures of spread (variance, standard deviation, quartiles), and probability tools (dice odds, coin flips, normal and binomial distributions). Every calculator is completely free, mobile-friendly, and requires no sign-up or download. All formulas follow standard statistical definitions used in textbooks worldwide, so students and professionals alike can trust the numbers.
