Mean, median, mode and range for any list of numbers.
Frequently Asked Questions
What is the difference between mean and median?
The mean adds all values and divides by the count. The median is the middle value when sorted. The median resists outliers: one very large salary barely moves the median but inflates the mean.
What is the mode?
The mode is the value that appears most often. A data set can have one mode, several modes, or no mode at all when every value appears the same number of times.
Which average should I use?
Use the mean for evenly spread data, the median for skewed data like incomes or house prices, and the mode for categorical or most-common questions like the most popular shoe size.
Is the Average Calculator free, and is my data private?
Yes. It is completely free and every calculation runs locally in your browser, so the numbers and dates you enter are never uploaded, stored, or shared with anyone.
