What is Average? What is the Mean?

In statistics, the mean of a set of numbers is the average value of those numbers. Find the average or mean by adding up all the numbers and dividing by how many numbers are in the set.

Average is the Same as Mean

Average and mean are both measures of central tendency. They tell us what the most typical number in a data set is, or which number best represents all values in the data.

How to Find the Mean

1. Count the number of values in your data set.
2. Add up all of the values to get the sum.
3. Divide the sum by the count.

Mean Formula

The mean (x̄) of a data set is the sum of all the data values divided by the count or size (n).

mean = x̄ = (Σxᵢ) / n
