Data Analytics

 

Introduction

  • Is it Data Science, Data Mining, and Data Analytics? All mean the same thing. There is a big craze with the term “data science” but there is not that much difference between a data mining, data analytics, and data science.
  • I prefer the term “data analytics”; in my opinion it carries less pomp and actually infers someone given to the serious science and art of meticulously discovering and extracting meaningful knowledge and wisdom from data and information.
  • I use the term “meaningful” in this regard since each company or entity for that matter seeks to extract information patterns or knowledge from a particular domain that is meaningful and useful to that particular organization. For example, law enforcement and local grocery stores might derive different patterns of information from car traffic data.
  • The goal of this tutorial is to provide a simplified and demystified understanding of data analytics a.k.a. data science, and provide examples that anyone can implement of their own.
  • The quantity of data is only increasing to the point that most of that data goes unprocessed – without anyone actually finding out what such data means.
  • Today folks are talking about big data – referring to extremely large quantities of data, and dark data referring to data that remain unprocessed, with no knowledge or information extracted from it.
  • The need for individuals who can extract information, knowledge, and wisdom from such data is a huge need and will remain so for the foreseeable future. We hope this set of tutorials provides a quick and simplified way to learn and apply data analytics skills to extract knowledge and wisdom from a diverse set of data domains.

Textbook

  • Although I will consider other resources, for this tutorial, I shall use as the textbook, “Data Mining: Introductory and Advanced Topics”, by Margaret H. Dunham, Prentice Hall, 2003, ISBN: 0-13-088892-3.

What is Data?

  • Merriam-Webster – data are facts or information used generally for calculations, analysis, and planning [1].

  • Wikipedia – Wisdom is the skill and ability to reason and then take action based on facts, information, knowledge, experience, and understanding [8].

Data Analytics
