Caducity of Idea aboutWave Function Collapse as well New Views on Schr dinger's Cat and Quantum Measurements

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 cat thought experiment or ¨ description of quantum measurements.
