Data Analysis with Open Source Tools--New from O'Reilly Media
A hands-on guide for programmers and data scientists

Sebastopol, CA--Collecting data is relatively easy, but turning raw information into something
useful requires that you know how to extract precisely what you need. With "Data Analysis with Open
Source Tools" (O'Reilly Media, $39.99 USD), intermediate to experienced programmers interested in
data analysis will learn techniques for working with data in a business environment.

"Every business is collecting data, and at a tremendous rate. The challenge is how to make it
useful," says data consultant and author Philipp K. Janert. "As corporations get more data-driven,
it is important to understand what you are doing with data. Otherwise, you are just adding to the
confusion. This book is the first on data analysis that was written for programmers, taking a
hands-on approach that is accessible for anyone with some software development skills."

You'll learn how to look at data to discover what it contains, how to capture those ideas in
conceptual models, and then feed your understanding back into the organization through business
plans, metrics dashboards, and other applications. Along the way, you'll experiment with concepts
through hands-on workshops at the end of each chapter. Above all, you'll learn how to think about
the results you want to achieve--rather than rely on tools to think for you.

"Data Analysis with Open Source Tools" will show you how to:

- Use graphics to describe data with one, two, or dozens of variables
- Develop conceptual models using back-of-the-envelope calculations, as well as scaling and
probability arguments
- Mine data with computationally intensive methods such as simulation and clustering
- Make your conclusions understandable through reports, dashboards, and other metrics programs
- Understand financial calculations, including the time-value of money
- Use dimensionality reduction techniques or predictive analytics to conquer challenging data
analysis situations
- Become familiar with different open source programming environments for data analysis

Advance Praise
"Finally, a concise reference for understanding how to conquer piles of data."
-Austin King, Senior Web Developer, Mozilla

"An indispensable text for aspiring data scientists."
-Michael E. Driscoll, CEO/Founder, Dataspora
