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.

About this tool
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.
Example. The numbers 1, 2, 2 and 5 give mean 2.5, median 2, mode 2, range 4, sum 10, min 1 and max 5.
Limit. Weighted mode rejects a negative weight and rejects a set whose weights sum to zero.
