How to Calculate the Pool standard Deviation
Hello There !
In this lesson I didn't understand how do you calculate the pool standard deviation, can you give me the formula ?
Or is it the same as the one for the pool variance ?
Thanks a lot !
Thanks for reaching out!
You can use the one for the variance and then take its squared root.
