A scaling relation of the anomalous Hall effect recently found in a ferromagnetic semiconductor (Ti,Co)O2 is compared with those of various ferromagnetic semiconductors and metals. Many of these compounds with relatively low conductivity $\sigma_{xx}\leq 10^{4}$ $\Omega$-1$\cdot$cm-1 are also found to exhibit similar relation: anomalous Hall conductivity $\sigma_{\text{AH}}$ approximately scales as $\sigma_{\text{AH}}\propto\sigma_{xx}{}^{1.6}$, that is coincident with a recent theory. This relation is valid over five decades of $\sigma_{xx}$ irrespective of metallic or hopping conduction.
