typically $language will already do for you.

First a warning: summing  the median and dividing by numbers of summands 
gives you what? imho only useless information. But anyway. A q&d awk 
script would look like

/^[0-9]/	{ s += $4; n++ }
END	{ print s/n }

If you really want to have the median of the last thirty days, 
recalculate them for yourself.
