Random noise is well distributed across the spectrum and really does not add the way correlated data does so there is a real increase in signal to noise ratio. This principle is used in all sorts of information theory applications in communications, weak signal work and optical systems. Integrating a number of detections of a signal buried in noise, the signal raises to a greater degree than random noise in fact. Binning pixel data of large arrays of tiny pixels results in significant improvements in signal to noise ratio. Nokia has a tiny sensor in the 808 model phone that has a 41mpx camera that allows combining pixels to improve DR and noise performance. The pixels are really tiny 1.4 micron yet by binning they are able to get excellent DR at moderately high ISO
I notice the improvement in every D800 image I downsample. You will notice it also.
