Data analysis is part computer science and part statistics. An important part of data analysis is validating your assumptions with real-world data to see whether there is a pattern, or a particular user behavior that you can validate. 

In this book, we are going to learn about data analysis from the perspective of the Haskell programming language. The goal of this book is to take you from being a beginner in math and statistics, to the point that you feel comfortable working with large-scale datasets. While mathematics is a big part of data analysis, we've tried to keep this book simple and approachable so that you can apply what you learn to the real world.
