python mean and standard deviation code example

Example 1: python standard deviation

import numpy as np
dataset=[13, 22, 26, 38, 36, 42,49, 50, 77, 81, 98, 110]
print('Standard Deviation:', np.std(dataset))

Standard Deviation: 29.694275542602483

Example 2: standard deviation python

import numpy as np
values=[1,10,100]
print(np.std(values))
values=[1,10,100,np.nan]
print(np.nanstd(values))
