About the average calculator

How do you calculate the average (mean)?

Add up all the numbers, then divide by how many numbers there are. For example, the mean of 2, 4, and 9 is (2 + 4 + 9) ÷ 3 = 15 ÷ 3 = 5.

What is the difference between mean, median, and mode?

The mean is the sum divided by the count. The median is the middle value when the numbers are sorted (the average of the two middle values if there is an even count). The mode is the value that appears most often.

How do you find the median of a list of numbers?

Sort the numbers from low to high. If the count is odd, the median is the middle number. If the count is even, the median is the average of the two middle numbers.
