Description

About the Book: Principles of Data Wrangling

A key task that any aspiring data-driven organization needs to learn is data wrangling, the process of converting raw data into something truly useful. This practical guide provides business analysts with an overview of various data wrangling techniques and tools, and puts the practice of data wrangling into context by asking, "What are you trying to do and why?"

Wrangling data consumes roughly 50-80% of an analysts time before any kind of analysis is possible. Written by key executives at Trifacta, this book walks you through the wrangling process by exploring several factors-time, granularity, scope, and structure-that you need to consider as you begin to work with data. Youll learn a shared language and a comprehensive understanding of data wrangling, with an emphasis on recent agile analytic processes used by many of todays data-driven organizations.

Appreciate the importance-and the satisfaction-of wrangling data the right way.
