Getting Started with Haskell Data Analysis

By: James Church

Overview of this book

Every business and organization that collects data is capable of tapping into its own data to gain insights how to improve. Haskell is a purely functional and lazy programming language, well-suited to handling large data analysis problems. This book will take you through the more difficult problems of data analysis in a hands-on manner. This book will help you get up-to-speed with the basics of data analysis and approaches in the Haskell language. You'll learn about statistical computing, file formats (CSV and SQLite3), descriptive statistics, charts, and progress to more advanced concepts such as understanding the importance of normal distribution. While mathematics is a big part of data analysis, we've tried to keep this course simple and approachable so that you can apply what you learn to the real world. By the end of this book, you will have a thorough understanding of data analysis, and the different ways of analyzing data. You will have a mastery of all the tools and techniques in Haskell for effective data analysis.

The central limit theorem

In this section, we'll be discussing the central limit theorem, which is essential to our understanding of normal distribution. Normal distribution is an important formula for the study of even basic statistics in data science. Data science, at its heart, is mathematical. We're transitioning away from the technical aspects of Haskell and file formats. First let's look at the central limit theorem before we introduce normal distribution, and then we're going to be exploring the parameters of normal distribution. So, here is the definition of the central limit theorem as per Wikipedia:

The central limit theorem (CLT) states that, given certain conditions, the arithmetic mean of a sufficiently large number of iterates of independent random variables, each with a well-defined (finite) expected value and finite variance, will be approximately...
