<mean.dist/>
This is a mean for 'continous ditributions' not 'discrete distibitions'
(in K-12 terminology).
It is not 'a funtion that describes the dist', but rather 'the density
funtion
of the dist' that must be integrated (for 'continuous real dists').
<sdev/> needs a square root added.
Better to define variance first and then say that sdev is the square
root of the variance. Remove 'arithmetical'. Remove f from variance,
then sdev and variance apply to any distribution.
Thus <moment/> may need generalizing too. Is it in K-14?
