# Best Data Science Books in 2020 (Vetted by Experts)

What are the best books for learning data science?

First things first: if you want to learn to *do* data science, the most important thing you can do is get your hands on some real-world data and start coding. Our learning platform is designed to do that, getting you hands-on and writing real code from day one. Even if you’re not using Dataquest, your primary approach to learning data skills should be *hands-on*.

But what can you do to keep learning in those moments when you’re not sitting in front of a computer? Read some data science books!

As a student we recently spoke with pointed out, ebooks are a great way to immerse yourself in data science at times when you can’t actually get hands-on with code — like on a bus ride, for example, or while waiting in line.

You can also listen to bools like podcasts if you use an ebook app with a “read aloud” feature, or decide to pay for an audiobook.

So what books should you read? Below, we’ve listed some of the best. And the even better news? Many of these books are totally free!

**Note**: Some of the links below are PDF links. We’ve tried to link to the free versions of books where possible.

## Non-Technical Data Science Books

(These are books that might help get you motivated to start or continue your data science journey, or help you better understand important issues in the data science field. You won’t learn many practical skills from them, but they’re good reads that help show how data and statistics are used in the real world).

* Weapons of Math Destruction* – One of the most popular nonfiction works about how “big data” and machine learning are not as unbiased as they might appear. Written by a former Wall Street quantitative analyst.

* Big Data: A Revolution That Will Transform How We Live, Work, and Think* – A good “big picture” read on how data and machine learning are changing lives in the real world — and on what else is likely to change in the future. If you’ve heard about the hype but aren’t really sure how data science can affect things, this is a good place to start.

* Naked Statistics: Stripping the Dread from Data* – A good read on statistics and data for the layperson. If you’re interested in learning data science but it’s been a while since your first math course, this is a great book to help you build confidence and intuition about how statistics are useful in the real world.

* Invisible Women: Data Bias in a World Designed for Men* – Understanding how biases in our data can create inequalities in the real world is critical for anyone working with data to understand. This book details how aspects of gender inequality can be traced to data that treats men as the “default.”

** Numsense: Data Science for the Layman** – A self-described “gentle” introduction to data science and algorithms, with minimal math. This is used as a textbook in some university courses, and it’s a good place to start if you’re interested in data but a little bit afraid of the math. (By the way, you don’t have to be good at math to learn coding — in fact, it doesn’t even really help).

* Everybody Lies: Big Data, New Data, and What the Internet Can Tell Us About Who We Really Are* – This book is essentially

*Freakonomics*for data science. It’s an interesting read that will also help you get an idea about how to approach answering different kinds of questions using data.

* Algorithms of Oppression: How Search Engines Reinforce Racism* – Another book on how algorithms contribute to inequality, this one focused on search engines. Algorithmic bias, and the ways it is created (and can be avoided) is really important for anyone who wants to work with data to understand.

## General Data Science Books

** The Elements of Data Analytic Style** – This book by Johns Hopkins professor Jeff Leek is a useful guide for anyone involved with data analysis, and covers a lot of the little details you might miss in statistics lessons and textbooks. It’s a pay-what-you-want book, so while you

*can*technically get this one for free, we recommend making a contribution if you can.

** The Art of Data Science** – Another pay-what-you-want book that takes a big-picture view of how to do data science rather than focusing on the technical nitty gritty of statistical or programming techniques.

** An Introduction to Data Science** – This introductory textbook was written by Syracuse professor Jeffrey Stanton, and it covers a lot of the fundamentals of data science and statistics. It also covers some R programming, but sections of it are very worthwhile reading even for those who’re learning Python.

** Social Media Mining** – This textbook from Cambridge University Press won’t be relevant for every data science project, but if you

*do*have to scrape data from social media platforms, this is a well-rated guidebook. Note that the site also includes links to some free slide presentations on related topics as well.

** The Data Science Handbook** – This book is a collection of interviews with prominent data scientists. It doesn’t offer any technical or mathematical insight, but it’s a great read for anyone who’s thinking about data science as a career and wondering what it entails, what roles are out there, and whether it might be right for them.

* Doing Data Science: Straight Talk from the Frontline* – A collection of talks from data scientists working at a variety of different companies that’s meant to cut through the hype and help you understand how data science works in the real world.

** Data Science for Dummies** – Laugh if you want, but these books provide good, clear introductions to a lot of important concepts. There’s also a

*Big Data for Dummies*book that’s worth taking a look at.

** Data Jujitsu: The Art of Turning Data into Product** – A good read on general data science processes and the data science problem solving approach from DJ Patil, arguably the most famous data scientist in the United States.

* Mining of Massive Datasets* – A free textbook on data mining with, as you’d expect from the title, a specific focus on working with huge datasets. Be aware, though, that it’s focused on the math and big-picture theory; it’s not really a programming tutorial.

* Designing Data-Intensive Applications* – This book is more about data engineering than data science, but it’s a good read for any aspiring data scientist who’s going to be creating production-ready models or who may have to do some data engineering work (which is not uncommon in data science roles, particularly at smaller companies).

* Data Science Job: How to Become a Data Scientist *– A book on the non-technical side of learning data science — how to build your data science career. The world of data science changes fast, but this book was self-published in 2020 so it’s relatively up-to-date, and several reviewers say it’s a good read for beginners. (Dataquest also has a data science job application and career guide if you’re interested in something that’s shorter and free)

## Python for Data Science Books

** Python Data Science Handbook** – An O’Reilly text by Jake VanderPlas that is also available as a series of Jupyter Notebooks on Github. It’s not for total beginners; it assumes some knowledge of Python programming basics (but don’t worry, we’ve got an interactive Python course you can take for that).

** Automate the Boring Stuff with Python** – This total beginner’s Python book isn’t focused on data science specifically, but the introductory concepts it teaches are all relevant in data science, and some of the specific skills later in the book (like web scraping and working with Excel files and CSVs) will be of use to data scientists, too.

** A Byte of Python** (PDF link) – Like

*Automate the Boring Stuff*, this is another well-liked Python-from-scratch ebook that teaches the basics of the language to total beginners. It’s not data-science-specific, but most of the concepts it covers are relevant to data scientists, and it has also been translated into a wide variety of languages, so it’s easily accessible to learners all over the globe.

** Learn Python, Break Python** – Yet another well-liked Python-for-beginners tome that encourages readers to learn Python by “breaking” it and watching how it handles errors and mistakes.
