sciPy stats.mean() function | Python

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]
