both the mean and the median are reasonable measures of central
tendency, which one you choose is up to you. You can get the adjusted
median prices while keeping weight and length at their median rather
than mean values in the following way:
*------------ begin example ----------
sysuse auto
qreg price weight length foreign
sum weight if e(sample), detail
local med_w = r(p50)
sum weight if e(sample), detail
local med_l = r(p50)
adjust weight=`med_w' length=`med_l', by(foreign)
*----------- end example ----------------
(For more on how to use examples I sent to the Statalist, see

Hope this helps,
