Through the generation of the UrQMD model, event statistics for the products of kurtosis (κ) and variance (σ 2 ) of net-proton and net-charge multiplicity distributions are carefully studied. It is shown that the statistics at RHIC/BES at √SNN < 19.6 GeV are not sufficient to use the method of centrality bin width correction (CBWC). Corresponding results are systematically underestimated. A way to improve the CBWC method is proposed. It can remove the statistical dependence of the data and also reduc...
