Hello
everybody,
I just
wanted to do an XYZ analysis, but I fail because of the standard deviation ...
This is
what the simplified example looks like:

At the end
I need a standard deviation per article…. But I do not know how to enter it….
So far, I
have grouped the articles so that article 1 only has one entry and the quantity
has 60. If I then do the standard deviation, every line comes up with 0 ...
Does anyone
have any idea how I can calculate the standard deviation for each article?
Many thanks
Best regards
David
