Measured is the transverse electrical resistance of YBa2Cu3O7-δ single crystals with different oxygen deficiency values (δ) in the temperature range Tc - 300 K. The experimental data are approximated by an empiric expression accounting for the fluctuation conductivity near Tc and the semiconductor-like resistance regime. Our analysis of the concentration dependences of the fitting parameters, in particular, reveals that the resistance temperature dependence is largely affected by the sample's nonhomogeneity. The latter, in turn, causes a Tc anisotropy and variable-range hopping conductivity between different phases. The deduced maximal values of the basal-plane coherence length, ξxy(0), are comparable with those for low-temperature superconductors.
