Calculating the arithmetic mean in Python
The term arithmetic mean is the average of the numbers. The mathematical formula to determine the arithmetic mean is to divide the sum of the numbers by the count. It is determined in Python in the following way.
- Use mathematical formulas.
-
Use the mean() function from the Python standard library, for example
NumPy,statistics,scipy.
Calculate the arithmetic mean using mathematical formulas in Python
Follow this procedure using mathematical formulas.
listnumbers = [1, 2, 4]
print("The mean is =", sum(listnumbers) / len(listnumbers))
Output:
The mean is = 2.3333333333333335
numpy.mean()Calculate the arithmetic mean
using the function in Python
NumPyThe standard library contains a function for determining the arithmetic mean in Python mean(). To do this, first import NumPythe library. Refer to the example below.
import numpy
listnumbers = [1, 2, 4]
print("The mean is =", numpy.mean(listnumbers))
Output:
The mean is = 2.3333333333333335
statistics.mean()Calculate the arithmetic mean
using the function in Python
statisticsThe library contains mean()a function for determining the arithmetic mean. To do this, first import statisticsthe library. Follow the example below.
import statistics
listnumbers = [1, 2, 4]
print("The mean is =", statistics.mean(listnumbers))
Output:
The mean is = 2.3333333333333335
scipy.mean()Calculate the arithmetic mean
using the function in Python
scipyThe library contains mean()a function for determining the mean. To do this, first import scipythe library. Here is an example.
import scipy
listnumbers = [1, 2, 4]
print("The mean is =", scipy.mean(listnumbers))
Output:
The mean is = 2.3333333333333335
