The Mean, Median and Mode Calculator takes any list of numbers and returns the three classic measures of central tendency, plus the range, sum and count. It is ideal for students, teachers and anyone summarising a data set without opening a spreadsheet. Paste your numbers and every statistic updates instantly.
How it works
You enter values separated by commas, spaces or new lines. The tool then computes:
- Mean — the arithmetic average: sum of all values divided by the count.
- Median — the middle value once the numbers are sorted. With an even count, it averages the two middle values.
- Mode — the value (or values) that appear most often. If every value appears equally often, there is no mode; if several tie, all are listed.
- Range — the largest value minus the smallest.
- Sum and count — the total and how many values there are.
Example
For the list 4, 8, 6, 4, 10:
- Sum = 32, count = 5, so mean = 32 ÷ 5 = 6.4.
- Sorted: 4, 4, 6, 8, 10 → median = 6 (the middle value).
- 4 appears twice, more than any other, so mode = 4.
- Range = 10 − 4 = 6.
| Statistic | Value |
|---|---|
| Mean | 6.4 |
| Median | 6 |
| Mode | 4 |
| Range | 6 |
| Sum | 32 |
Everything is computed in your browser, so the data you enter is never uploaded.
