Range calculator

Find the range, minimum and maximum of a list of numbers.

The Range calculator turns Numbers (comma-separated) into Range, Minimum, Maximum, instantly and for free. For instance, with Numbers (comma-separated) = 4, 8, 15, 16, 23, 42 it returns Range = 38, Minimum = 4 and Maximum = 42.

How to use it

  1. Enter your values: Numbers (comma-separated).
  2. Read the result instantly: Range, Minimum, Maximum.

Frequently asked questions

How does the Range calculator work?

It takes Numbers (comma-separated) and derives Range, Minimum and Maximum from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

A single value: Numbers (comma-separated). Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Numbers (comma-separated) = 4, 8, 15, 16, 23, 42, the calculator returns Range = 38, Minimum = 4 and Maximum = 42. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Numbers (comma-separated) = 4, 8, 17, 18, 28, 53 instead, Range goes from 38 to 49 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Numbers (comma-separated) = 4, 8, 15, Range comes out at 11. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Summarising a dataset before drawing conclusions from it, checking whether a difference between two groups is real, and putting an interval around an estimate.

What is the most common mistake?

Reading a p-value as the probability that the hypothesis is wrong. It is the probability of seeing data at least this extreme if the null were true — a different statement, and a much weaker one.

What is the difference between the Range calculator and the Interquartile range (IQR) calculator?

This one returns Range and Minimum; the Interquartile range (IQR) calculator returns Q1 (25th percentile) and Q3 (75th percentile). That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Coefficient of variation calculator is the closest one after this: Compute the coefficient of variation (CV) of a dataset — its relative variability.

What else is worth having open alongside it?

Correlation coefficient calculator and Expected value calculator — they come up in the same task often enough to be worth a second tab.
