mean() Function of statistics Module in Python (Example)


In this Python programming tutorial you’ll learn how to apply the statistics.mean function.

The post looks as follows:

Let’s start right away!


Creation of Example Data

First, let’s create some example data.

my_list = [4, 3, 8, 7, 8, 4, 4, 1, 5]    # Create example list
print(my_list)                           # Print example list
# [4, 3, 8, 7, 8, 4, 4, 1, 5]

The previous output of the Python console shows the structure of our example data: We have constructed a list object containing nine integer values.


Example: Apply mean() Function of statistics Module to List

The Python programming code below illustrates how to apply the mean function of the statistics module to get the average of a list of values.

If we want to use the functions of the statistics library, we also have to load statistics:

import statistics           # Import statistics

In the next step, we can apply the mean function of the statistics module to return the arithmetic mean of our data:

print(statistics.mean(my_list))          # Apply statistics.mean function
# 4.888888888888889

As you can see, the mean of our data is 4.889.
