Statistics Calculator

Descriptive statistics (mean, median, variance, quartiles) and linear regression with correlation, computed in your browser.

Enter at least one number.

How to use

  1. For descriptive statistics, paste numbers separated by commas, spaces or new lines.
  2. Mean, median, mode, variance, standard deviation and quartiles appear instantly.
  3. For linear regression, enter one “x, y” pair per line to get the regression line and correlation.
  4. In regression mode you can also predict y for any x.

Notes

Variance and standard deviation are shown both as population (dividing by n) and sample (dividing by n−1) versions. Quartiles use linear interpolation (the same definition as R's type 7). Entries that are not numbers are ignored and reported. All computation happens in your browser.

FAQ

Why does the mode sometimes say “none”?
If every value occurs only once, no mode exists and the tool says so. Values tied for the highest frequency (at least two occurrences) are all listed.
Can it handle large datasets?
A few thousand points are fine, though speed depends on your device. Inferential statistics such as hypothesis tests and confidence intervals are not covered.
