Data Science Books to learn for Free and Paid

As the world gets more data-savvy, the need to make sense of all that has increased many folds. What started as the “Sexiest Job of the 21st century” is now being implemented across verticals and industries, thanks to rapid development in research, tools and technology. If you are new to the field of data science and would like to start somewhere but don’t know where here is a list of data science books to read in order to know what the field is about and perhaps know how you can make a career out of it.


If you are a beginner and have not done any hands-on data science before, your first step should be to know what this field is all about. Here are some data science books that you can read to know about the subject. Do remember that the aim here is to know what this field is all about and not get into jargon and technicals right away. We will get to that in the Intermediate and Advanced sections;

Data Science for Dummies

data science for dummies

This book touches upon what data science is and as it reads, it’s for people who have little to no knowledge of what this field is about. You can get your hands on it and understand what it is to work on data science problems and build solutions that help companies make data-driven decisions.

Python Data Science HandbookFree

python data science handbook

Although there are tools that can be used to do analysis without programming, for hardcore data science and deeper research you would need to code. If there is one programming language you have to learn and master if you want to do Hands-on data science, it is python. The language is easier compared to other programming languages and comes with plenty of pre-built packages and a supporting developer community. This book by Jake VanderPlas, covers the python you would need for data science work and is a good and broad introduction to the Python data science toolkit. It covers an introduction to the NumPy library including concepts such as arrays, computations on arrays and data types in Python. It also gives a good, beginner-friendly introduction to data analysis with Pandas and machine learning with Scikit-learn. Grab it for free here! And, if you are new to python totally, it is better to read ‘Learn Python the right way‘ before reading the Data science handbook.


ISLR & ESLR data science books

The ISLR & ESLR bundle is considered one of the best books to read if you want to know the fundamentals of Machine learning, statistics and how optimization functions are determined. The book covers the fundamentals needed and is a great read if you want to know the theory behind basic algorithms. There are also coding examples in R for you to code along. You can read the book here.

ESLR on the other hand delves deep into the mathematical foundations with no coding at all. It gives you a strong idea of why many models work the way they work, along with the how. It can be considered as the book that you read once you get a good grip on ISLR. If you do not have a good foundation in Statistics and Linear Algebra, and if you are new to the field of Data Science, reading this directly will be quite challenging and you may drop off. You can read the book here.

Practical Statistics for Data Science

practical statistics for data science book

This book by Peter & Andrew bruce talks about statistics as used in the real world by data scientists. Statistical methods are a key part of data science, yet very few data scientists have any formal statistics training. Courses and books on basic statistics rarely cover the topic from a data science perspective. This practical guide explains how to apply various statistical methods to data science, tells you how to avoid their misuse, and gives you advice on what’s important and what’s not. You can grab the book here.

Think Bayes

The age-old debate between frequentists vs bayesian’s might continue for a long time, and it only gets bigger every day. Most statistics books cover Machine Learning from a frequentist standpoint and are in fact considered successful compared to Bayesian methods due to computation and algorithmic capabilities. Bayesian methods are used in other areas as well, and if you would like to understand the basics behind them using Python, then this book is a good read.

Mathematics for Machine LearningFree

Packed with clear explanations, visualizations, and examples, the book covers all the essential machine learning techniques in depth. You also learn about PyTorch, one of the widely used Deep learning frameworks and also scikit-learn and build ML models and pipelines using them.

Feature Engineering for Machine Learning

Feature Engineering for Machine Learning

Feature engineering is a crucial step in the machine-learning pipeline, yet this topic is rarely examined on its own. It is one of the important steps that could differentiate a great model from an average one. With this practical book, you’ll learn techniques for extracting and transforming features—the numeric representations of raw data—into formats for machine-learning models. Each chapter guides you through a single data problem, such as how to represent text or image data. Together, these examples illustrate the main principles of feature engineering.

Rather than simply teaching these principles, authors Alice Zheng and Amanda Casari focus on practical application with exercises throughout the book. The closing chapter brings everything together by tackling a real-world, structured dataset with several feature-engineering techniques. Python packages including NumPy, Pandas, Scikit-Learn, and Matplotlib are used in code examples. This book also covers feature engineering for texts, images and tabular data. Grab the book here.
