Basic Statistics of NumPy Array

Basic Statistics of NumPy Array. The following shows basic statistics Mean, Median, Correlation coefficients, Standard deviation of a NumPy array of the Python NumPy module. 

 

import numpy as np

 

In [1]:

arr = np.array([1.2, 1.4, 1.9, 1.7, 1.6])
np_2d = np.array([[1.2, 1.4, 1.9, 1.7, 1.6], [37.7, 56.3, 62.8, 49.7, 62.5]])

 

In [2]:
