In mathematics, the “Standard Deviation” is a statistical calculation that quantifies the amount of variation or dispersion in a dataset. In Python, we can compute the standard deviation using various modules, such as statistics, NumPy, or Pandas. To calculate/determine the standard deviation ...

df.get_values().mean() df.get_values().std() Except that in the latter case, it uses mean() and std() function from numpy. It's not a problem for the mean, but it is for std, as the pandas function uses by default ddof=1, unlike the numpy one where ddof=0....
