How to find the mean
The mean, or arithmetic average, is found by adding every value together and dividing by the number of values. It gives a single number that represents the centre of the data set. This tool also reports the sum, count, median, minimum, and maximum so you can see the full picture at a glance.
Frequently asked questions
How do you calculate the mean?
Add up all the numbers to get the sum, then divide by how many numbers there are. The mean is the arithmetic average of the set.
What is the difference between mean and median?
The mean is the sum divided by the count, while the median is the middle value when the numbers are sorted. The median is less affected by extreme outliers, so this calculator shows both.
