Mean, Median, Mode Calculator

Calculate the mean, median, mode, and range of any data set instantly. Paste a list of numbers and get all central-tendency measures plus count and sum.

Mean, Median, Mode Calculator

Numbers (comma, space, or new-line separated)

Method

How this calculator works

Mean = (sum of values) ÷ (count). Median = the middle value of the sorted list, or the average of the two middle values when the count is even. Mode = the value(s) occurring most often. Range = max − min.

Paste or type your numbers into the box, separated by commas, spaces, or new lines.
Click Calculate to process the list — invalid or blank entries are ignored automatically.
Review the mean, median, mode, range, count, and sum in the results panel.

Examples

Worked examples

Real numbers, end-to-end results.

2, 4, 4, 6, 8

Mean = 4.8

Sum 24 ÷ 5 values = 4.8; median 4; mode 4.

10, 20, 30, 40

Median = 25

Even count: average of the two middle values (20 and 30).

3, 3, 7, 7, 9

Mode = 3, 7

Two values tie for most frequent — a bimodal set.

Use cases

When to use it

Summarizing test scores, survey responses, or grades.
Analyzing measurements in science and engineering labs.
Comparing sales, prices, or performance figures.
Teaching or learning basic descriptive statistics.

FAQ

Frequently asked questions

What is the difference between mean, median, and mode?

The mean is the arithmetic average (sum divided by count), the median is the middle value when the data is sorted, and the mode is the value that appears most often. Together they describe the center of a data set from different angles.

How do I enter my numbers?

Type or paste your values into the box separated by commas, spaces, or new lines. The calculator automatically ignores blank entries and stray separators, so you can copy directly from a spreadsheet column.

What happens if my data has no mode?

If every value appears exactly once, there is no mode and the calculator reports 'No mode'. If two or more values tie for the highest frequency, all of them are listed as modes (a multimodal set).

How is the median found for an even number of values?

When the count is even there are two middle values after sorting. The median is the average of those two middle numbers. For an odd count, the median is simply the single middle value.

What is the range and why is it useful?

The range is the difference between the largest and smallest values (max − min). It gives a quick measure of how spread out the data is, though it only reflects the two extreme points.
