standard deviation：标准差 ，也称均方差（mean square error），是各数据偏离平均数的距离的平均数，它是离均差平方和平均后的方根，用σ表示。标准差是方差的算术平方根。标准差能反映一个数据集的离散程度。平均数相同的，标准差未必相同。 m...

In this example, I’ll show how to calculate the standard deviation of all values in a NumPy array in Python.For this task, we can apply the std function of the NumPy package as shown below:print(np.std(my_array)) # Get standard deviation of all array values # 2.3380903889000244...
The term standard deviation sounds like something you hear in a statistics class, but don’t dismiss it as an overly technical term just yet. It can be used in different aspects of our lives. A teacher can use the standard deviation of marks of her students in an exam as a metric to ...
