  We reconcile the phenomenon of mesoscopic conductance fluctuations with the
single parameter scaling theory of the Anderson transition. We calculate three
averages of the conductance distribution: $\exp(<\ln g>)$, $<g>$ and $1/<R>$
where $g$ is the conductance in units of $e^2/h$ and $R=1/g$ is the resistance
and demonstrate that these quantities obey single parameter scaling laws. We
obtain consistent estimates of the critical exponent from the scaling of all
these quantities.
