Use of geometric mean .. in good data analysis
...-- do the things you learned to
do quickly without too much thought, because things must happen
fast ---to hopefully save the other's life.
Here: Do log transform all such variables with further ado,
and only afterwards start your (exploratory and more) data analysis.
Now, mean(log(y)) = log(geometricmean(y)),
where mean() is the arithmetic mean as in R
{mathematically; on the computer you need all.equal(), not '==' !!}
I.e., according to Tukey and all the other experienced applied
statisticians of the past, the geometric mean is the "best thing"
to do for such positive right-sk...

Use of geometric mean for geochemical concentrations
A statistical question, not specific to R.
I'm asking for a pointer for a source of definitive descriptions of what
types of data are best summarized by the arithmetic, geometric, and harmonic
means.
As an aquatic ecologist I see regulators apply the geometric mean to
geochemical concentrations rather than using the arithmetic mean. I want to
know whether the geometric mean of a set of
