Dynamical fluctuations in global conserved quantities such as baryon number,strangeness, or charge may be enhanced near a QCD critical point. Chargedependent results from new measurements of dynamical $K/\pi$, $p/\pi$, and$K/p$ ratio fluctuations are presented. The STAR experiment has performed acomprehensive study of the energy dependence of these dynamical fluctuations inAu+Au collisions at the energies $\sqrt{s_{NN}}$ = 7.7-200 GeV using theobservable, $\nu_{\rm dyn}$. These results are compared to previousmeasurements and to theoretical predictions. Various proposed scaling scenariosthat attempt to remove the intrinsic volume dependence of $\nu_{\rm dyn}$ andto simplify comparisons between experimental measurements are also considered.Constructing an intensive quantity allows for a direct connection tothermodynamic predictions.
