GUIDE

How to use this calculator

Use the statistics calculator to turn a list of numbers into a compact summary with count, sum, mean, median, minimum, maximum, range, and spread measures. It is useful for checking small datasets without uploading them anywhere.

Calculation method

Mean = Σ values ÷ count; range = maximum − minimum

Quick examples

Summarize five test scores
Compare the mean and median
Find the range of daily measurements
Inspect standard deviation for a small sample

Steps

Enter one number per line or separate values with commas.
Check that the list contains only the values you want to summarize.
Select Calculate statistics.
Compare central tendency and spread rather than relying on one metric alone.

What is the mean?

The mean is the sum of all values divided by the number of values.

When is the median useful?

The median is the middle value after sorting and can better represent a typical result when a dataset has extreme outliers.

Does the calculator send my dataset to a server?

No. The values and summary are processed locally in your browser.
