Combined mean and standard deviation from a collection of NumPy arrays of different shapes

0 votes

Consider that I have a numpy array like this

(682, 89, 138)
(2668, 76, 89)
(491, 62, 48)

How can I calculate the mean and standard deviation of all three above arrays combined? Is it even possible to do this for different sized dimensions? Or do I need to reshape it before getting the mean and std?
