Data Analysis, Mathematical Statistics, Machine Learning, Data Mining: Similarities and
Differences

Abstract
An attempt is made to bring some structure in the meanings of the title subjects based on the perspectives at which
they view the data. A rigid framework for Data Analysis is proposed pointing out its role in augmenting the
knowledge of a phenomenon the data relate to. In particular, the task of summarization as a general problem is
discussed. The ingredients of a data analysis problem are described as a base for positioning of various approaches
in data analysis and mathematical statistics.
Introduction
The similarities between the subjects mentioned in the title relate to two fundamental facts: (i) all of them
develop methods and procedures to process data, and (2) any data processing algorithm or procedure may
belong to any, or better to say, all of them. The differences are in the different perspectives. The
difference in perspectives does not affect the procedures but it does affect the choice of them and, even
more so, interpretation of concepts and results.
Before I go any further, let me give an example by presenting two concepts that are common at analyzing
data: the average and correlation, in the different perspectives.
