Data Science Platform Market was valued at USD 95,3 billion in 2021 and the data science market is estimated to reach – worth $322.9 billion by 2026.

“Torture the data, and it will confess to anything.” (Ronald Coase, Economics, Nobel prize Laureate)

“Without big data analytics, companies are blind and deaf, wandering out onto the web like deer on a freeway.”

~ Geoffrey Moore, management consultant and author of Crossing the Chasm

The U.S. Bureau of Labor Statistics reports that the demand for data science skills will drive a 27.9 percent rise in employment in the field through 2026. Not only is there a huge demand, but there is also a noticeable shortage of qualified data scientists.

What is data science?

Data science is the study of data to extract meaningful insights for business. It is a multidisciplinary approach that combines principles and practices from the fields of mathematics, statistics, artificial intelligence, and computer engineering to analyze large amounts of data.

Here are the top free Data Science Books for students and people must add to their list in 2023 in order to improve data science skills and to get data science jobs.

1. Practical statistics for data science  By Peter Bruce & Andrew Bruce

Read it for free here.

practical stats for data science

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.

2. Learn the Python the right way

Python is the programming language of choice for data science. Learning the fundamentals of programming in this language is therefore one of the first things beginners in the field should learn. This book is not specific to programming for data science but covers the general concepts of writing Python code.

learn the python the right way

This book assumes no prior knowledge of programming and gives an introduction to the Python language and basic general coding principles. Each chapter contains a complementary Youtube video which helps to further explain the concepts covered.

The authors of the book have also made available a set of hands-on tutorials, containing over 15 practical Python projects to put your learnings into practice.

3. Deep learning for coders with fastai and pytorch: Ai applications without phd

This book is a practical first introduction to deep learning. It is aimed at coders so an understanding of Python programming is essential before diving into this book. However, it does not assume a deep understanding of maths and statistics and includes some excellent and simple explanations of the theory behind deep learning.

7. The Field Guide to Data Science by Booz Allen Hamilton

This book built by several hands by Booz Allen Hamilton employees introduces the theme of Data Science, presents the tools necessary to work with the area, and expands the background a little. It basically works as an introduction to the subject, but it is very well written, with infographics and illustrations that are especially creative. And there is a section that should be printed by everyone working in the field, a guide on how to choose the right technique for each piece of the problem.
