Statistics Calculator
Paste a list of numbers to get descriptive statistics — count, sum, mean, median, mode, range, variance, and standard deviation.
Separate with commas, spaces, tabs, or newlines. Non-numeric content is ignored.

How to use the statistics calculator
Paste or type your numbers separated by commas, spaces, tabs, or newlines — anything non-numeric between values is ignored. The tool parses out the numeric tokens and computes the descriptive statistics you usually want for a dataset.
- Enter your data in the textarea. Both integers and decimals are accepted.
- Every result updates as you type. The tool shows the count, sum, mean (average), median (middle value), mode (most frequent), min, max, and range.
- Two sets of spread statistics are shown: sample variance and standard deviation (dividing by n−1) and population variance and standard deviation (dividing by n). Pick whichever matches how the data was collected.
Sample vs population
If your numbers are every possible value (the whole population), divide the squared deviations by n to get variance. If your numbers are a sample drawn from a larger population and you want to estimate that population's variance, divide by n−1 instead — this corrects for the underestimate that would otherwise creep in. Most introductory statistics classes use the sample formulas by default.
