📈 Mean Median Mode Calculator

About this Mean Median Mode Calculator

One box, the whole descriptive-statistics starter kit. Paste any list of numbers and get the count, sum, mean, median, mode, range, variance and standard deviation — both the population variance and the sample (n−1) version. Ideal for homework, quick data checks and making sense of marks, measurements or survey scores.

How to use it

1. Paste your numbers separated by commas, spaces or new lines.
2. Click Calculate statistics.
3. Read the mean, median and mode together — they tell different stories about the same data.
4. Scroll for range, variance and standard deviation to see how spread out the values are.

Example

For 4, 8, 15, 16, 23, 42: the mean is 18, the median is 15.5, there is no mode, and the standard deviation is about 12.79.

Frequently asked questions

When should I use the median instead of the mean?

When the data has extreme values — one very high salary or one failed test — the median stays representative while the mean gets dragged toward the outlier.

What is the difference between population and sample variance?

Population variance divides by n and describes your exact data; sample variance divides by n−1 and estimates a bigger population from a sample. Both are shown.
