Overview of this book

As increasing amounts of data are generated each year, the need to analyze and create value out of it is more important than ever. Companies that know what to do with their data and how to do it well will have a competitive advantage over companies that don’t. Because of this, there will be an increasing demand for people that possess both the analytical and technical abilities to extract valuable insights from data and create valuable solutions that put those insights to use. Starting with the basics, this book covers how to set up your numerical programming environment, introduces you to the data science pipeline, and guides you through several data projects in a step-by-step format. By sequentially working through the steps in each chapter, you will quickly familiarize yourself with the process and learn how to apply it to a variety of situations with examples using the two most popular programming languages for data analysis—R and Python.

Introduction


This project will introduce you to the US employment data provided by the Bureau of Labor Statistics (BLS) of the United States government.

This data can be downloaded as a compressed comma-separated value (CSV) file at http://www.bls.gov/cew/data/files/2012/csv/2012_annual_singlefile.zip , which contains the single file 2012.annual.singlefile.csv. This file has 15 columns and about 3.5 million rows.

The QCEW is a quarterly collection of data, via the corporate tax collection system, related to employment and wages reported...
