It is impossible to catalog and classify all examples of data Analysis, let alone list them on an arbitrary scale of “greatness.” Data analysis isn’t one finite set of events with a beginning and an end. It is a way of looking at the world around us. Indeed, if the definition is taken to extremes, consciousness itself could be seen as data collection and analysis: with further collection and analysis being driven by insights of previous iterations.
Of course, this conscious loop has many branches. To map them all out would create an infinite recursive fractal, where each step is subject to further inspection, action, and change.
