0 0 1 minute read

scipy.stats.mean(array, axis=0) function calculates the arithmetic mean of the array elements along the specified axis of the array (list in python).

It’s formula –

Parameters :
array: Input array or object having the elements to calculate the arithmetic mean.
axis: Axis along which the mean is to be computed. By default axis = 0

Returns : Arithmetic mean of the array elements based on the set parameters.

Code #1:

# Arithmetic Mean  
   
import scipy 
  
arr1 = scipy.mean([1, 3, 27])  
   
print("Arithmetic Mean is :", arr1)

Output:

Arithmetic Mean is : 10.3333333333

Code #2: With multi-dimensional data

# Arithmetic Mean  
   
from scipy import mean 
  
arr1 = [[1, 3, 27],  
        [3, 4, 6],  
        [7, 6, 3],  
        [3, 6, 8]]  
   
print("Arithmetic Mean is :", mean(arr1))  
  
# using axis = 0 
print("\nArithmetic Mean is with default axis = 0 : \n",  
      mean(arr1, axis = 0)) 
  
# using axis = 1 
print("\nArithmetic Mean is with default axis = 1 : \n",  
      mean(arr1, axis = 1))   

Output:

Arithmetic Mean is : 6.41666666667

Arithmetic Mean is with default axis = 0 : 
 [  3.5    4.75  11.  ]

Arithmetic Mean is with default axis = 1 : 
 [ 10.33333333   4.33333333   5.33333333   5.66666667]
