I would appreciate it if someone could send me information regarding how
Excel calculates the Skewness of a group of data.
I've searched both text books and the Internet for the correct formula for
determining skewness but I have come across at least three different methods
that are used.
As I understand it the calculation uses the second, third (and fourth?)
moments to make the calculations but I find that different authors come up with
different values.
Thanks in advance
