How to Learn Data Science with No Coding Background?

Wondering how to learn data science without a coding background?

A career in data science can sound pretty daunting when you are a non-programmer. Subjects like coding, mathematics and statistics are important for data science but that doesn’t mean they are impossible to learn. With proper guidance and dedication it is simply easy-peasy. 

So, to help you out, in this article we are going to guide you with not just how you should go about learning data science but what to learn, the tools to master and the books to read.

Let’s get started.   

8 Crucial Tips To Start Your Data Science Journey

If you want to master data science and have a successful career in it, keep these 8 tips in mind. 

1. Say ‘No’ to Shortcuts – Work from the Ground Up!

First, start with the basics of statistics and mathematics required for data science. Develop an understanding of basic machine learning algorithms and try solving a real-life situation using it. 

Another essence here is to stay away from ‘phony’ courses, those promising to make you a data-scientist in, say, 21-days! There can never be a replacement of hard work for a technically sophisticated job such as Data Scientist. So, enroll only with authentic and professional institutes possessing high credibility and success rate.

Take your time while learning data science and be consistent. The basic idea here is to get a command of the fundamentals, step by step. 

2. Level Up Your Programming Skills

This is one crucial skill you need to have to be a successful professional in this field. Programming languages like C, C++, R/Python, Java are something of a routine in this field. You can follow these pointers to boost your programming skills.

  • Start with the basics of C as this is the base language using which many other programming languages are built.
  • Understand the concept and up your programming game, try developing example algorithms into working programs.
  • Websites like TopCoder, CoderByte, Project Euler hold programming contests. You might want to try any of these to enrich your programming capability.
  • Proceed to R/Python once you’re through with the basics.

Following the above guide-points will take you a step closer to your dream profession.

3. Start Exploring and Loving Data

As a Data Scientist,  you’re going to deal with data day and night. Statistics, mathematical crunching, organizing and segmenting data would be a routine part of your job. Data modeling can be taxing and quite complicated to the beginner. So, it is advised that you get involved with data, statistics, and mathematics as soon as possible.

Once you are comfortable with numbers and loads of data crunching, deriving relations between seemingly unrelated data, seeing the big picture, telling a story through numbers, this is going to be a fruitful job for you.

4. Give Yourself Homework

Let us say, at this point, you will be training yourself from scratch for the technical soundness required from a data-science professional. When you feel comfortable with data modeling and the programming languages, start taking up projects to work on your own.

  • Choose a field you want to work in like healthcare, sports, crime, social justice, etc. and take a relevant dataset about the field from the internet. You’ll find plenty of datasets at websites like
  • Process and crunch the dataset. Play with your data however you like. Again, be consistent and try thinking beyond the obvious.
  • You can use tools like Microsoft Azure, Google Cloud, etc. for creating meaningful data-science projects. Gradually, you will build up a portfolio of such projects to add to your credibility.
  • Follow a daily schedule religiously. Be as consistent as you can and keep practicing. 

5. Sharpen Your Analytical Skills 

While practicing what you’ve learned from your books and other sources on datasets, think unconventional and try to develop insights about the data. 

Start questioning the random world around you. All the whys, whats and hows are going to help you out. There are gaps, unmet needs and demands in all the aspects of human life. But hey! That is why you are going to help them as a data-scientist. Keep the following tips in mind.

  • Focus on the story the data is telling, what it is conveying and whether it is leading to another prediction.
  • Segment the data on as many as possible bases. Subject it to algorithms that you understand and try it with new algorithms.
  • Be very consistent and pay attention to the outputs. Prepare summative reports. Also, take part in online data mining operations like the ones held at
  • Critically examine your performance and resolve issues if any. Keep a record of these outputs and add them to your portfolio.

6. Network with Professionals

Once you have gathered a bunch of outputs, get in touch with someone who is already a data scientist. We recommend that you start building a strong professional network in this field. Choose someone who has experience of two years or more as a data scientist and has been in the field for a long time. You can ask him/her to examine your work and how it reflects your capabilities. This way:

  • You’ll get a professional opinion on how you are doing. Knowing where you stand regarding expertise, you can better yourself rather easily.
  • Make it a point to discuss the current trends, salary criteria, expertise expectations, real-life impacts of the job on personal lifestyle, etc. You’ll have better insights about what you’re signing up for.
  • If they like your work, ask them for a recommendation or referral. Always carry your portfolio if they have you meet someone.

7. Start with An Entry-Level Job

Do not wait till you become the solitary authority on Data Sciences. Remember we talked about starting from the ground-up? Apply for an entry-level job once you’ve got an idea of the basics of data sciences.

Send your resumes to companies that deal in ML or AI. Marketing giants also employ data scientists to crunch data for them and device relevant predictions.

You can ask your professional friends about the pay packages and other standard practices before appearing for the interview. Keep their suggestions and advice in mind and proceed accordingly.

This point makes sense as you are switching to a whole new field. You should join online forums which are dedicated to Data Science, read blogs and articles regarding latest developments, keep your journal throughout your learning process. Each learning is a brick to the fort you are building. And the fort here is data-science. To build it and keep yourself updated follow the below tips.

  • When learning advanced concepts like cognitive learning, deep learning, neural networks, keep a pen and paper nearby and take notes if you have to.
  • Applications like EverNote also come in handy for taking notes.
  • If you are taking a course from somewhere, make brief notes in class. Focus more on understanding than writing.
  • Take part in various mining competitions, coding competitions, etc. as often as you can. Competing refines your skills and promotes strategic thinking.
  • Read trusted journals like IEEE, Springer, Elsevier for latest developments in data sciences, AI and ML. These will help you align with the industry events and standards.

These were some necessary tips to guide you through your data science journey. Now let’s see what all tools can add to your improvement in the field.

Pros: This book discusses advanced concepts like data mining, prediction, and inference about ML. It takes a comprehensive approach towards related concepts like regression techniques, support vector machines with flexible discriminants, ensemble learning, undirected graph models, etc. and uses examples freely. Exercises provided at the end of each concept have some remarkable problems and inspire strategic and out-of-the-box thinking.

Cons: It requires the student to have a good hold of statistics and ML basics, preferably with R/Python. (as the book focuses on building predictive models and draw inferences from them)

Verdict: From the point of view that it is a book for intermediate to advanced levels of learning, the language it uses is pretty simple and understandable. It is, however, advisable to read the first volume of this book (mentioned above) before beginning with this one.

Apart from these books, one could refer to online sources like web tutorials, blogs, and journals for new milestones and developments in the Data Sciences. 


Data Science is challenging, especially, when you are switching to this domain without any coding/programming experience. But most data scientists will tell you that it’s a job worth all the effort. So, buckle up and embark upon your journey!
