Re: Correlation Between Mean and Standard Deviation

Is there any relevance, in principle, to the correlation between the

if "related data sets" means independent samples for the same
object of interest I'd say ..no..no relevance at all.


Suppose I claimed that a greater standard deviation in such a data
set implied greater diversity of elements in that set. Would that be
a reasonable assumption? Thanks.

The greater the variance (then its square root) the greater
the "diversity", being the variance a quantitive
measure of the dispersion around the mean.
However this doesn't have much to share with the correlation
among your data sets as above.
