How to use the Average, Median & Mode calculator
- Type or paste your numbers separated by commas or spaces.
- Read the mean, median, mode, range and standard deviation.
How it's calculated
Show the formula
Mean = sum ÷ count · Median = middle value when sorted · Mode = most frequent value
Median is the middle value when sorted. Mode is the most frequent value. Standard deviation here is the population formula.
Worked example

| Median | 15 |
| Mode | 15 |
| Smallest / largest | 9 / 30 |
| Range | 21 |
| Standard deviation | 6.0828 |
Tips
- The median is better than the mean when a few values are very large or small.
