  Investigated idea was actuated by the old opinion that a measurement of a
quantum observable should be regarded a as a single deterministic sampling.
But, according to the last decades studies, such observables are veritable
random variables and their measurements must imply significant sets of
statistical samplings. So one finds the indubitable caducity of the approached
idea. Contiguously the respective finding allows to put into a new light the
controversial questions like the Schrodinger's cat thought experiment or
description of quantum measurements.
