How it works
- Mean = sum of all the numbers ÷ how many numbers there are.
- Median = the middle value once the numbers are sorted. With an even count, it is the average of the two middle values.
- Mode = the value that appears most often. If every value appears once, there is no mode.
- Range = largest value − smallest value.
Frequently asked questions
Which average should I use?
The mean uses every value, but outliers pull it. The median is better when a few very large or small values would distort the mean, such as house prices or salaries.
Can a list have more than one mode?
Yes. If two or more values tie for the most appearances, they are all modes.
