We investigate the degree to which the scaling functions $f\left({\psi }^{\prime }\right)$ derived from inclusive electron-nucleus quasielastic scattering define the same function for different nuclei. In the region where the scaling variable ${\psi }^{\prime }<0\mathrm{}$, we find that this superscaling is experimentally realized to a high degree.
