NumPy array var() function in Python is used to compute the arithmetic variance of the array elements along with the specified axis or multiple axes. We
Example 1 explains how to compute the variance of all values in a NumPy array. In order to achieve this, we can use the var function of the NumPy library as shown in the following Python code: print(np.var(my_array))# Get variance of all array values# 5.466666666666667 ...
