Basic statistics from raw numbers
Descriptive statistics summarize a dataset into a few key numbers: the mean (average), median (middle value), mode (most frequent), and measures of spread like standard deviation and variance. This calculator computes all of them at once from a list of numbers you paste in — useful for analyzing survey results, test scores, sensor readings, or any numeric data. All computation happens locally.
Key features
- Mean, median, mode, range, min, max, sum, count
- Standard deviation (sample and population)
- Variance, quartiles (Q1, Q2, Q3), and IQR
- Handles decimal numbers and negative values
Frequently asked questions
What's the difference between sample and population standard deviation?
Use sample (n−1) when your data is a subset of a larger population. Use population (n) when your data IS the entire population.
What if there's more than one mode?
If multiple values tie for most frequent, they're all listed. If no value repeats, the dataset has no mode.
Is my data uploaded?
No. Statistics are computed locally in your browser; your numbers never leave your device.
