The range measures how spread out the data is.
How to use this calculator
- Paste or type the numbers.
- Press Calculate. The data is sorted for you to find the median.
Worked example
Data: 2, 4, 4, 4, 5, 5, 7, 9
Sum = 40 and n = 8, so the mean is 5.
The middle two values are 4 and 5, so the median is 4.5. The mode is 4 and the range is 9 − 2 = 7.
Frequently asked questions
What if no value repeats?
Then there is no mode. If several values tie for most frequent, all of them are listed.
Mean or median — which should I use?
The median is less affected by extreme values, so it often describes skewed data better.
