How to use Mean Median Mode Calculator
The mean, median, mode and range calculator computes all six core descriptive statistics from a list of numbers in one step: mean (average), median (middle value), mode (most frequent value, including multimodal sets), range, sum, and count. Paste any numbers separated by spaces, commas, or newlines and get a complete summary table instantly — ideal for homework, data analysis, statistics coursework, and quick data exploration.
- Paste or type your numbers into the input box, separated by spaces, commas, or line breaks.
- Click Calculate to compute all statistics.
- Read the results table showing count, sum, mean, median, mode, and range.

Definitions and formulas
Mean (arithmetic average) = sum of all values ÷ count. Median = the middle value when data is sorted ascending; for even counts, the average of the two middle values. Mode = the value(s) that appear most frequently; a data set is bimodal if two values share the highest frequency, multimodal if more than two do, and has no mode if all values appear equally often. Range = maximum value − minimum value. These four measures together describe the centre, spread, and typical values of a distribution, forming the foundation of descriptive statistics.
| Statistic | Formula | What it tells you |
|---|---|---|
| Mean | Σx / n | The balancing point of the data |
| Median | Middle value (sorted) | The centre value; robust to outliers |
| Mode | Most frequent value(s) | The most common value; can be multimodal |
| Range | max − min | Total spread of the data |
| Sum | Σx | Total of all values |
| Count (n) | Number of values | Sample size |
Choosing the right measure of central tendency
The mean is the most commonly used measure but is sensitive to outliers. A single very large or very small value can skew the mean dramatically. The median is more robust — half the values fall above it, half below — making it the preferred measure for skewed data such as income distributions and house prices. The mode is useful for categorical data (e.g. the most popular product) and for understanding frequency patterns. In a perfectly symmetrical distribution, mean, median, and mode are all equal; in right-skewed data, mean > median > mode; in left-skewed data, mean < median < mode.
Worked examples
Set with a mode
Inputs: 2, 3, 3, 5, 7
Result: mean 4 · median 3 · mode 3 · range 5
Even count median
Inputs: 4, 6, 8, 10
Result: mean 7 · median 7 · range 6
Glossary
- Mean
- The arithmetic average of a data set: sum divided by count.
- Median
- The middle value in a sorted data set; the average of the two middle values for even-sized sets.
- Mode
- The value that appears most often in a data set; a set can be bimodal or multimodal if multiple values share the highest frequency.
- Range
- The difference between the maximum and minimum values in a data set; a simple measure of spread.
