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 measures of central tendency. They tell us what is the most typical number in a data set, or which number best represents all the numbers in the data set.
How to Find the Mean
- Count the number of values in your data set
- Add up all of the values to get the sum
- Divide the sum by the count
Mean Formula
The mean x̄ of a data set is the sum of all of the data values divided by the count or size n.
\[ \text{mean} = \overline{x} = \dfrac{\sum_{i=1}^{n}x_i}{n} \]Calculator Use
