For instance, if a company wants to improve its sales revenue, it will hire a data scientist to analyze business performance data and make the right decision to maximize it.
The pressing need for a data scientist in almost every business and industry has prompted this field to become one of the most sought-after job titles. If you are still wondering if you should consider learning Data Science, then here’s what you need to know – companies are pushing boundaries to hire skilled Data Scientists, even if it means shelling out astronomical figures to close these positions.
As you know, the skill gap in this field has resulted in more vacant positions than skilled Data Scientists.
Understanding the Data Science Industry Growth
As the world moves into the realm of digitalization, more and more data is being generated. This, in turn, is opening doors to increased demand for Data Science technology and tools. To improve productivity, and make sense of this vast data set, big data, data mining, machine learning, data science, and data analytics are forming the backbone of leading businesses worldwide.
Be it any industry, domain, or field, the surge in demand for skilled Data Scientists is proof enough that this industry will have unprecedented growth. In 2018, we said that the world would need one million Data Scientists.
Fast-forward to three years now – According to the latest market research report, the valuation of the Data Science industry is predicted to touch $140.9 billion by 2027.In 2019, it was recorded to touch $37.9 billion. These statistics for Data Science proof of how the market is anticipated to grow.
Nothing can slow down this growth, not even a Pandemic like Covid-19 that has hit the world in its worst forms.
It is important you know when it comes to where the Data Science industry is heading. This will help you determine what to learn, where, and how to learn. It takes no Einstein to predict that the growth of the Data Science industry isn’t faltering any time soon. Interpretability continues to grow in leaps and bounds.
How can I say this?
In 2019, Salesforce acquired Tableau, while Google expanded its horizon with Looker. These two were the biggest deals that prompted experts to believe in the steady growth that Data Science will have. Apart from these two, many more small acquisitions happened –
- Lionbridge acquired Gengo
- DataRobot acquired three companies – ParallelM, Cursor, and Paxata
- HPE acquired MapR
These are just a few acquisitions I mentioned. 2019 saw an intensive M&A activity and consolidation in the data science industry.
The idea of leading names trying to leverage their assets by bringing in further consolidation in the data science market points out that these names want to expand their capabilities to leverage AI better.
This is your ideal time to get started with Data Science Certification courses.
Data Science Courses: Eligibility
You already know what data science is by definition since you are here looking up related courses. So I will skip the definition part.
To get started with Data Science courses, you must first understand if you have the eligibility. It is not always about your specialization in your higher studies or graduation. Eligibility to learn Data Science also requires reasoning skills. Technicalities can be learned with perseverance, but logical reasoning and eye-for-details are something that you need to have to get started.
Data Science has four core elements –
- To acquire information
- To organize the data
- To discover trends
- To help device future course of actions
Data Scientists take upon the responsibility of taming unstructured data and creating meaning. The four elements drive a Data Scientist to create business-driven decisions.
Analyzing your eligibility is essential. As I said, your past qualification will not determine if you want to take a data Science Certification Course. For instance, Siva Devarakonda, the director of Data Science for Noodle.ai, has a background in electrical engineering and later took up a data science online course. Siva believes that Data Science cannot be taught from scratch. When you are going through a Data Science Syllabus, you realize the areas you want to learn or master.
To check where you stand, start with the following questions:
- What skills you will need?
- What is your current skill status?
- What kind of job role do you want to explore?
You’ll know you are ready to learn in real time when you have specific answers to these three questions.
If you are still looking blank, I will give you a context to start analyzing your skills and eligibility. To become a Data Scientist, you can opt for a university-based course (if you have the time and money), or you can opt for some of the professional Data Science certification courses. There are many free Data Science courses as well (which we will discuss in detail later).
Whatever mode of learning you pick, your starting point is here. Check out if you have these skills to get started:
-
Knowledge in Statistics
Statistics for Data Science is more like oxygen for living. You cannot afford to excel in Data Science if Statistics is not your friend. If someone asks me, ‘Hey, how to become a Data Scientist?’ I’d say, ‘Get a grip on your Statistics’.
Why?
Statistics form the backbone of data science. It is what helps in structuring vast chunks of data and deriving useful pieces of information from it. With Statistics, you can process all the information and predict business outcomes successfully.

Mathematics for Data Science (and Machine Learning)
Practical implementation comes in the form of a skilled mathematician. If you are scared of mathematics, you either opt out of Data Science or eliminate your fear.
You have to understand that Data Science and Machine Learning are inter-dependable concepts. Despite being a variant in treatments, they both work together. You will need mathematics to optimize machine learning principles as a data scientist.
-
Programming Languages
There are a few programming languages that are necessary to get started with a data science course.
- Microsoft Excel – Advanced Knowledge.
- Python
- R
- SQL
Data Science is a vast field. To master it, you must know all these underlying fields.
Essential Resources to Get Started With Data Science
Let’s get you into your learning robes without much ado. The first step is getting your hands on the right resources. We will break this into two sections:
- Data Science Skills
- Data Engineering Tools
A complete Data Science Certification course is step two. I have put together some amazing reading resources to get started with Data Science.
1. Data Science Skills – Resources to get started with
For easier understanding, I will break this section into five categories: Foundation Skills, Technical Skills, Business Skills, Miscellaneous Skills, and Practice resources.
(1) Foundation Skills
The first answer to How to Become a Data Scientist lies in learning the two foundation skills:
Programming and Data Wrangling
To acquire this skill, you will have to know at least one kind of scripting language. Ideally, I recommend you start with Python or R. Whichever you choose, ensure you do one thing at a time.
To decide which is better, read our guide on Python vs. R.
Python Resources to get started with:
- Learn Python the Hard Way – A highly recommended online book for beginners looking for a complete course in Python.
- Interactive Book: How to Think Like a Computer Scientist – Covers all concepts in mastering the art of solving complex problems.
- Why you should learn Python: Our guide in helping you take the right route to a good learning experience.
R Resources to get started with:
- Introduction to Data Science with R: Online book for beginners.
- Probability and Statistics
I have already discussed the importance of Statistics in learning Data Science. This skill helps you with A/B testing, conditional probability, and many other skills. Resources to start with:
- Think Stats: Statistics and Probability for Programmers – A well-designed resource that you can download and learn at your convenience.
- Harvard Stats 110: Probability – A video series for deeper understanding.
(2) Technical Skills
You will require several technical skills to convert raw data into something meaningful. Let’s take a look at these skills:
Data Collection:
You will always need the right data set to make the right inferences. Data Collection can be done in four ways –
- Handling internal data that belongs to your company is collected through various business operations. Such data is usually relevant.
- Online data sets that let you prototype before you invest in copyrighting it.
- API to legally and programmatically access data sets that are collected by other companies.
- Using Web crawling and Web scraping tools needs to be done responsibly.
Resources to get started with Data Collection:
- R: httr Quickstart Guide – A tutorial on how to use the HTTR library
- Python Web Scraping Libraries – A resource by Elite Data Science on Python Web Scraping.
SQL:
We have already talked about SQL and resources to get started with.
Data Visualization:
This skill is helpful for the explanatory analysis of data. You can start with Data Visualization with R or Python.
Applied Machine Learning:
Machine Learning Scientist and Data Scientist are two different job roles, but they are still related. Machine learning is a large concept that encompasses sub-concepts like Data Science. The resource you can use is Machine Learning by Andrew Ng – A video series to learning machine learning.
(3) Business Skills
Business skills are also soft skills that you must have to become a skilled data scientist. Being a data scientist is not only about learning technical know-how. You must also have the aptitude to lead. You will need to understand how a business works, how it envisions its value proposition, and how you can creatively think of solutions and effectively communicate your ideas. Below are some of the soft skills that you must have. Follow the resources mentioned for each skill.
- Communications:
There is no substitute for this skill. If you cannot communicate your ideas, chances are someone else will. Often data scientists face challenges when it comes to effectively communicating mathematical and technical solutions. In this scenario, you will need to be precise, clarify your explanation, and align your ideas with the organization. I will recommend a TED talk titled The Best Stats you’ve ever seen. This TED talk will show you how you can communicate data in a fun way. Not everything needs to be boring!
- Innovative bend of mind:
Data Scientists are supposed to tame unstructured data and make valuable use of data. This requires creative thinking and an innovative approach. After all, there is more than one way of solving a problem. It is up to you how best you can find the most effective solution. Follow this TED talk on The Art of Innovation by Guy Kawasaki for a better learning curve.
- Business Strategy Building:
Another core job role of a data scientist. You are not responsible for only analyzing data; you are also supposed to help make improve business decisions. Hence, it is inevitable that you are expected to have better business strategy knowledge than anyone else. Watch the TED talk How Data Will Transform Business to understand the correlation between technology and business.
(4) Miscellaneous Skills
These are more in-demand skills. You can learn these at your convenience.
- Natural Language Processing (NLP): Follow the video series from Stanford NLP.
- Recommendation Systems: Also known as Collaborative Filters, this skill has the most success in the eCommerce domain. Follow the Recommendation engine Tutorial for an introduction to advanced learning.
- Time Series Analysis: This involves indexing data by time. Read The Little Book of R for Time Series – an online book for step-by-step learning.
(5) Practice Resources
Practice resources serve two major purposes:
It helps you practice all the concepts you have learned and turn you into a better data scientist.
You have projects to show your employers, giving you an edge over others.
Check out our list of 20 project ideas that you can try.
