The three measures of central tendency

The mean, median, and mode are the three main measures of central tendency, each answering "what is the typical value" in a different way, and as a mean median mode range tool it adds the range too. It also works as a plain average calculator when you just want the mean. The mean is the sum divided by how many numbers there are, the everyday average. The median is the middle value once the numbers are sorted, which is not thrown off by one very large or small value. The mode is the value that appears most often, and a set can have one mode, several, or none.

When to use each

The mean uses every value, which makes it precise but sensitive to outliers: one huge number pulls it up. The median ignores how far away the extremes are, so it is often a fairer typical value for skewed data like incomes or house prices. To find the mode, look for the value that appears most often; the mode is the only one that works for categories and is useful when you care about the most common result rather than a central number.

A worked example

Take 5, 7, 7, 9, 12. The sum is 40 and there are five numbers, so the mean is 8. Sorted, the middle value is 7, so the median is 7. The value 7 appears twice and the rest once, so the mode is 7. The range is 12 minus 5, which is 7.

FAQ

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

The mean is the average, the sum divided by the count. The median is the middle value in order. The mode is the most frequent value. They can all differ, especially for skewed data.

How do I find the median?

Sort the numbers and take the middle one. If there is an even count, the median is the average of the two middle values. The tool does this automatically.

Can there be more than one mode?

Yes. If two or more values tie for most frequent, the set has multiple modes. If every value is unique, there is no mode. The tool reports each case.

What is the range?

The range is the largest value minus the smallest, a simple measure of spread. It appears in the results alongside the count and the smallest and largest values.
