Hi,
Just a stupid statistical question to z-scores:
Given a set "S" of numeric values the z-score of these values is given
by:
(S - mean(S))/sd(S)
??? What range of values do I expect afterwards? -1 to 1 mainly? When
my
standard deviation is smaller than one, then I get my range scaled up
rather
than down, but in any case and that is the main thing my standard
deviation
is scaled to 1. So do I have to worry if my new value range is scaled
up?
