The conceptual basis of statistical operator is analysed by comparing two differentways of introducing it in quantum mechanics -subsystem method and ensemblemethod. The one-to-one correspondence of the statistical operator to the physicalstate properly characterized is contrasted with the deficient degrees of freedom of thewave function. The paradoxical features of the Einstein-Podolsky-Rosen typethought experiment and of the reduction of wave-packet at observation can be dis-solved in the reformulation of quantum mechanics in which the statistical operator,instead of the wave function, is primarily introduced as the fundamental quantity todescribe the state.
