The mean uses every value, so one extreme number moves it. The median is the middle value of the sorted list and resists outliers, which is why incomes and house prices are usually reported as medians. The mode is the most common value and is the only one that works for categories such as shoe sizes or favourite colours. A list can have more than one mode, and it can have none.
Find the mean, median and mode of any list of numbers. The mean, median and mode are the three standard measures of a typical value. Paste a list of numbers and this calculator returns the count, the sum, the mean (the arithmetic average), the median (the middle value of the sorted list), every mode (the most frequent value, which can be more than one) and the range, with the sorted list for checking. Definitions follow the NIST/SEMATECH e-Handbook of Statistical Methods.
Mean, median and mode answer different questions. The mean is the balance point, the median is the middle, and the mode is the most common value. Seeing all three side by side shows whether the data are skewed. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Mean, median and mode from one list, plus the count, sum, range, minimum and maximum.
If two values tie for most frequent, both are listed. If every value appears once, the tool says there is no mode.
The numbers are sorted so you can check the median by eye and spot outliers.
The calculation runs in your browser, and nothing is uploaded.

The mean adds all values and divides by the count, so it moves toward large outliers. The median is the middle value after sorting, so it ignores how extreme the outliers are. For skewed data such as incomes, the median is usually the better summary of a typical value.
Sort the list and average the two middle values. For 1, 2, 3, 4 the middle pair is 2 and 3, so the median is 2.5.
If every value appears exactly once, no value is more common than the others, so the list has no mode. If two or more values share the highest count, all of them are modes.
Yes. Any finite number works, including decimals and negatives. Values are compared as numbers, so 2.5 and 2.50 count as the same value.
