How to Find the Average
The average, or mean, is a measure of the central tendency of a set of numbers. It is a single number used to represent the center, or typical value, for a larger set of numbers.
The average is one of the fundamental measurements for a data set in statistics and is used as the basis for several other measurements.
There are several types of averages, including arithmetic averages, geometric averages, weighted averages, and even harmonic averages. The calculator above solves the arithmetic average, also called the arithmetic mean.
You can find the mean using a formula.
The average formula to find the mean for a set of numbers is:
average = sum / count
Thus, the average of a set of numbers is equal to the sum of the numbers divided by the count of the numbers.
Find the Average in Three Easy Steps
So, you can find the average using the formula above in three steps.
Step One: Find the Count
The first step to find the average is to count the number of values in the data.
Step Two: Find the Sum
The second step is to add all of the numbers together to calculate the total sum of the numbers.
Step Three: Find the Average
The final step is to use the average formula above by dividing the sum of the numbers by the count. The resulting value is the average of the data.
While the average, or mean, is commonly used, it is just one measure of the center for a data set. Other commonly used measures of center are the median and mode.
You can also use our mean, median, mode calculator to find other measures of center for your data.
These other measurements are typically used since the average measurement can be easily skewed by outliers (extreme values) in the data.
For example, if you are trying to find your average grade for the year when you received 7 A grades but got one D grade, your average grade might be a B.
But, the median and mode of your grades is an A since they are less skewed by one grade in the whole set, which is an extreme outlier.
