We present measurements of the variances and covariance of $[p_{\\mathrm{T}}]$ and $v^{2}_{n}$, along with their dimensionless ratio, for Au+Au collisions at various beam energies: $\\sqrt{\\textit{s}_{NN}}$ $=$ 14.6, 19.6, 27, 54.4, and 200~GeV. Our measurements reveal a distinct energy-dependent behavior in the variances and covariances.
