## Introduction

The selection process of data scientists at Google gives higher priority to candidates with strong background in statistics and mathematics. Not just Google, other top companies (Amazon, Airbnb, Uber etc) in the world also prefer candidates with strong fundamentals rather than mere know-how in data science.

If you too aspire to work for such top companies in future, it is essential for you to develop a mathematical understanding of data science. Data science is simply the evolved version of statistics and mathematics, combined with programming and business logic. I’ve met many data scientists who struggle to explain predictive models statistically.

More than just deriving accuracy, understanding & interpreting every metric, calculation behind that accuracy is important. Remember, every single ‘variable’ has a story to tell. So, if not anything else, try to become a great story explorer!

In this article, I’ve compiled a list of must read books on statistics and mathematics. I understand, mathematics has no extreme. Hence, I’ve enlist only those books which will help you to connect with data science better.

Note: Books which are made free to access by the registered authorities have been mentioned in this article. If not, a link to amazon bookstore is provided.

## End Notes

The books listed in this article are selected on the basis of their reviews and depth of topics covered. This is not an exhaustive list of books. But, I found it’s almost too easy to get confused while deciding ‘from where to begin?’ In such situations, it is advisable to start with this list.

In this article, I’ve listed some most helpful books on statistics and machine learning. It has been found that people tend of neglect these topics in pursuit of quick success. But, that’s not the right way. Hence, if you aim for a long term success in data science, make sure you learn to create stories out of maths and statistics.

Have you read any of these books ? Which book on mathematics and statistics has helped you the most ? Please share your suggestions / reviews in the comments section below.

Wow! That’s a long list of books. Hoping to thoroughly read one of these.

Welcome Sreedhar!

Thanks a lot!

Hi,

The list of books are really helpful. Can you have a post on complete path to learn (or rather brush up) all the maths / stats / probability from scratch. I have too much material and resources now, but don’t know where to start from and how to progress.

Thanks

Hi,

I have the same concern.

So if someone can guide us it will be great

Thanks in advance

Hi Debarpita

Here’s what you are looking for: http://www.analyticsvidhya.com/blog/2016/02/free-read-books-statistics-mathematics-data-science/

Yes. i am also talking about the same list. But which book should I start with :)… and then how to progress ahead.

Start with Introduction to Statistical Learning.

Thanks a lot for the references. They are a must read, and most of them Free!

For those trying to learn about it’s a great help…

Wow. You have really compiled a list of useful books. Super! I had read think stats but the others were gems! Super, gonna read into more math, now.

I also own a copy of Discovering Statistics using R. It is really a nice book. Thank you for the list.

Hi All,

I am much interested in Big data Programme and its implemented in my organization. Seek to learn this upcoming technology. As I have almost 3.6 years exp as database developer and much interest in data related works. . But my background qualification is B.A general then 3 years Diploma in (Software engineering) , Microsoft certification in .Net Development.

But moving forward i heard that the programme is covered only for who have engineering degree, Mathematics, Economics, Statics. Hence pl humble request to all pl suggest on same as future perspective.

Thanks , Ravi

Hi Ravi

I understand your trouble and would like to help you in this regards.

Your education qualification is not at all a problem considering your experience in IT. May be, your organization might have put a selection filter but other big data courses don’t do that. Here is a list of top certifications in big data in 2016 – http://www.analyticsvidhya.com/blog/2016/01/top-certification-courses-sas-r-python-machine-learning-big-data-spark-2015-16/#seven

Completing any of these certification will surely add to your skills and job possibilities.

Hi, I wanted to ask you a few questions. Can I message u personally?

Hello Yash

You can ask me questions at discuss.analyticsvidhya.com. Do tag me.

Hello Manish.

I am working on geotechnical instrument data (just excel plotting) as a database engineer since last 4 years. I am from B.E (ECE) background. and interested in data science.

Plz suggest is this beneficial to me for carriar growth?

Hi,

This is Suresh, I have completed B.sc Zoology and passed out 2006. Now I am working in BPO sector. Now I want to change my domain so I selected for Business analytics course. Please suggest me, I am eligible for this course and can I get the job also. If I want to this course what I need too do? Please advise me. I went and asked one of the Analytics Institute they told me, I am not eligible for this course and suppose if I complete the course No one take it for Business analytics jobs they told me like that.

Awesome list, Manish. The first two books on statistical learning are goldmines of knowledge. The book by Devroye et al looks extremely rigorous and challenging although it could be used by anyone with [really] strong mathematical foundations in real analysis, (measure theoretic) probability and related subjects. Thanks for recommending this book, it may probably be the next book on my “To-Study” list. Would you mind if I recommend a few foundations books so that people who wanna study these books have a good background?

Hi Manish,

Nice collection, one more best book which i can suggest for data science newbies is “An introduction to Data Science” by Jeffrey Stanton, Syracuse University & Robert W. De Graaf. i hope we can learn basic Statistics and R programming at a time with this book.

thanks
