In this papet, by virtue of the Cauchy-Schwarz operator inequality due to J.I. Fujii., we show the covariance-variance operator inequality via the geometric operator mean which differs from Bhatia-Davis's one and estimate the upper bounds. By our formulation:we bhow a Robertson type inequality associated to the conditionaı expectation on a finite von Nuemann algebra.
