Using the Mean, Median, Mode, Range Calculator
A dataset can have several modes or no repeated value at all. The calculator reports tied modes rather than picking one arbitrarily. Sorting happens internally, so you do not need to enter observations in order.
Worked example
Use the example inputs below to reproduce this result. These are the form's starting values, not recommended targets. Changing your inputs updates your result above; this worked example stays fixed for comparison. Results are rounded for display.
Example inputs
- Numbers, separated by commas
- 2, 4, 4, 6, 9
Example result
- Count
- 5
- Sum
- 25
- Mean
- 5
- Median
- 4
- Mode
- 4
- Range
- 7
- Population standard deviation
- 2.3664319
Method and assumptions
The mean is sum/count; the median is the middle sorted value; all equally frequent repeated modes are reported.
Check what the data represents
A statistical result is only meaningful in relation to the observations and assumptions behind it. Keep track of whether values describe a whole population or a sample, whether observations are independent, and which distribution the method uses. More decimal places cannot compensate for a sample that does not represent the question you are trying to answer.
Common question
Which average should I use for a skewed dataset?
There is no universal choice. The median often describes a typical observation when extreme values pull the mean, while the mean remains useful for totals and further arithmetic.
