Range Calculator (Statistics)

Paste a list of numbers and get the mean, median, mode, range, sum, min and max at once — or compute a weighted average with full steps.

Separate numbers with commas, spaces or new lines. A decimal comma like 3,14 is understood — separate such numbers with spaces or new lines.

Result

This page opens the average calculator focused on the range: paste your numbers and the range card is highlighted in the results, with the minimum and maximum shown as separate cards right beside it so the arithmetic is visible.

The range is the simplest measure of spread: range = maximum − minimum. For the list 2, 4, 4, 4, 5, 5, 7, 9 the largest value is 9 and the smallest is 2, so the range is 9 − 2 = 7. A small range means the values are packed tightly together; a large one means they are widely scattered.

Because the range uses only the two extreme values, a single outlier can inflate it dramatically — which is exactly why this calculator also prints the sorted list and the full set of statistics from the same input, letting you judge whether the spread comes from the whole list or from one stray number.

Accepted Formats & Rules

  • Mean, median, mode(s), range, sum, count, minimum and maximum from one list of numbers.
  • Weighted average mode: value and weight pairs, one per line, with a step-by-step product table.
  • Sorted copy of your list plus honest mode detection, including a clear "no mode" verdict.

Key Benefits

✓ One paste gives you every basic statistic at once: mean, median, mode, range, sum, count, min and max.
✓ Numbers can be separated by commas, spaces or new lines, and decimal commas like 3,14 are understood.
✓ Everything is computed locally in your browser — your data never leaves the page.

Use Cases

  • • Paste a column of exam scores or survey answers and get the mean, median and mode in one run to see the typical value and whether outliers skew it.
  • • Compute a weighted course grade from "grade: credits" pairs — the step table shows every grade × credit product before the final average.
  • • Check the spread of monthly expenses or sensor readings at a glance: range, min, max and the sorted list come with every calculation.
