Back in 2012, the Harvard Business Review called data science “the sexiest job of the 21st century.” Not much has changed since then. If anything, the job of a data scientist has grown even hotter. According to a 2019 report by Indeed, there’s been an almost 30% increase in demand for data scientists year over year and nearly 350% jump since 2013. 

The demand for data scientists far outstrips supply. A 2018 LinkedIn survey found a shortage of more than 150,000 people with data science skills in the U.S. alone. As many as 50% of data scientists who already have a job get contacted at least once a week about new opportunities. 85% are contacted about once a month. This talent crunch means that, on average, a data science job stays vacant for 45 days. It comes as no surprise, then, that when businesses finally manage to attract data science talent, they pay them well. According to Glassdoor, as of June 2020, the average data scientist salary in the U.S. is $113,309

For employment-focused students, studying data science is a no-brainer. But not everyone has thousands of dollars to spare on a data science degree (or the time to do it, for that matter). Online courses offer a cost-effective alternative to degrees and the field of data science benefits largely from e-learning. As long as you can stay the course as a self-paced learner, you can outperform anyone with a traditional degree in data science. That is, if you choose the right online course.

These are the best data science courses you can take online.

Best Data Science Courses

Best Overall: Data Scientist Nanodegree (Udacity)

Data Scientist Nanodegree (Udacity)

  • Data science certification provided upon completion
  • Helps you create a personal data science project portfolio
  • Includes many quizzes and projects
  • Developed in collaboration with tech companies
  • Career services provided post-graduation


  • Some prerequisite knowledge required

This class covers the most important data science concepts such as data manipulation, machine learning, and big data.

Udacity’s “Data Scientist Nanodegree” is our pick for the best overall data science course. We like it for many reasons, but what truly sets it apart from the rest is how career-oriented it is. 

In this program, all students are guided through the process of developing their very own data science portfolios through practical real-world student projects. Not only are these projects good for putting theory into practice, but another big benefit of having a demonstrable portfolio of projects is that you can show them to job recruiters. Nowadays, an effective portfolio is just as, if not more effective, than a degree.

As for the skills you’ll be learning here, the program aims to teach you how to gather, manipulate, analyze, and visualize data using Python and its packages, such as NumPy, Pandas, and SciPy. The program covers a wide range of data-related topics in its 4-month curriculum, including wrangling, analysis, visualization, and MapReduce.

The classes are taught through video lessons and include quizzes and interesting assignments. For example, after the first lesson, you’re asked to use NumPy and Pandas to forecast the passenger survival rate on the Titanic. And the syllabus also covers other important data science concepts such as data manipulation, machine learning, and big data.

The Data Scientist Nanodegree is, without a doubt, a superb course on data science. It covers all the most critical data science topics and even lets you build data science projects from start to finish. It’s also worth a mention that Udacity’s career services are offered to all Nanodegree students, giving extra value to career-building students.

For these reasons and more, we consider Udacity’s Data Scientist Nanodegree to be the #1 best online course for learning data science. If you don’t meet the prerequisite knowledge requirements for this course, consider starting with the “Programming for Data Science in Python” Nanodegree from Udacity instead (or if you need R in your work, Udacity also offers a “Programming for Data Science in R” Nanodegree). It’s just as good but more beginner-friendly.

Data Science Online Bootcamp (Thinkful)

Best Overall: Data Science Online Bootcamp (Thinkful)

  • 1-on-1 mentorship from data science experts
  • Excellent career services
  • Study for free until you land a data science job earning $40k+
  • Specialization options enable you to personalize your curriculum


  • Upfront tuition is expensive without an ISA and issues reported with payment model

This program comes with a star-studded mentor lineup and a curriculum that outshines most degrees.​

To kick things off, we have Thinkful’s Data Science Online Bootcamp. Right off the bat, keep in mind that this program is NOT like your typical Udemy course. The curriculum is much closer to a Master’s degree than to the average MOOC. This also means that the admissions process vets applicants more selectively than most other online learning platforms.

Passing the admissions process, while demanding, is a task worth undertaking. That is because all admitted students are met with a one-of-a-kind data science curriculum that has numerous benefits over its competitors. These benefits include:

  • Biweekly 1-on-1 meetings with expert mentors;
  • Best-in-class post-graduation career services;
  • Data science specialization options based on your career goals;
  • Personal capstone projects that can be showcased to employers.

Before getting into the nitty-gritty of big data analysis, the program introduces new students to the basic concepts of data science through a prep course. This covers an introduction to Python and its packages, probability and statistics, and a quick primer on career planning. After this prep course, the students dive head-first into the core principles of data science, with lessons on SQL, supervised/unsupervised learning, and many, many more. For a first-hand overview of the syllabus, have a look at Brendan Martin’s post on the program.

To sum it up, Thinkful’s data science program truly is the best of its kind. But, due to its length and stricter-than-average admissions process, it’s not a one-size-fits-all type of program. But, we felt it easily deserved the title of THE best data science course on the market.


What is a data science course?

A data science course is any course that goes over important data science concepts. While the content featured in each data science course varies, any good course will teach you how to:

  • Understand whether data is meaningful (via statistics and probability).
  • Program in either Python or R (or both)
  • Use popular packages and workflows in your language of choice.
  • Write SQL queries.
  • Use machine learning algorithms and models.
  • Process large datasets with Hadoop or Apache Spark.
  • Visualize data with software like Tableau and Matplottlib.

The majority of data science courses include hands-on exercises. These give you room to practice your data science skills and help you consolidate your newfound knowledge. Many data science courses also incorporate a capstone project, which means that you get to build something from scratch, like a new visualization or a data-driven website.

How to learn data science online

Can a total beginner learn data science? Sure, here’s how you can learn data science online without any prior knowledge:

1. Enroll in an online course

The easiest way to learn data science online is to take a data science course. However, not all data science courses are the same. Some just skim the surface of data science, whereas others are truly comprehensive.

Also, some data science courses may have prerequisites. For example, Coursera’s Data Science Specialization, which we mentioned in our list above, requires students to have at least some Python programming experience and knowledge of regression. On the other hand, Thinkful’s Data Science Online Bootcamp has no such requirements and is suitable even for absolute beginners.

2. Learn the theory

As you’re learning the practical elements of the curriculum, you’ll no doubt come across some of the theory behind the code you’re implementing.

The advice that most data scientists give is this: learn the theoretical elements ALONGSIDE the practical aspects, not before. That way, you’ll retain more as you learn because you will understand the context of the theory.

Many online data courses go over the theory and provide additional readings and reference material. However, you’ll probably also want to do your own research for more advanced coverage of data science concepts.

3. Practice, practice, practice!

As cliche as it sounds, practice really does make perfect.

Don’t stop learning when you get to the end of an online data science course. Whether it’s a personal data science project or a Kaggle competition (more on these below), find something that motivates you to keep building on your existing data science skills.

Projects are also amazing for immediate feedback on areas that might need improvement. For example, if you’re working on a project and get stuck on whatever package you need to use, you know that you should probably study that area further.

Another good thing about competitions and personal data projects is that they allow you to build a data science portfolio. A comprehensive portfolio will show potential employers that you are both competent and passionate about data science.

Why study data science?

Below are a few key reasons why you should consider studying data science.

1. We live in a data-driven world

It’s true what Joris Toonders said in a 2014 Wired article, data is, indeed, “the new oil of the digital economy.” 

Today, almost every company, regardless of how big or small it is, relies on data. Data analytics allows organizations to improve their performance, grow their business, and, ultimately, gain a competitive edge over their peers. 

With at least 59% of enterprises using big data analytics in some form, being able to work with data is an essential skill to have.

2. You’ll always have options

Pretty much every industry leverages the power of data. That means that as a data scientist, you can work across different industries and sectors, from healthcare and pharmaceutical to manufacturing and entertainment.

You’re not going to be stuck with just one job title and the same responsibilities for the rest of your life, either (unless you want to). 

A data science certification will equip you with important transferable skills, which means that you could end up working as a business intelligence analyst, database manager, or machine learning engineer. 

But that’s just a snapshot of what you could do — the possibilities are, literally, quite endless.

3. You’ll never be unemployed

Quant Hub reported 37% year-on-year growth in data scientist job listings in 2019. 

Even COVID-19 hasn’t stopped the rise of data science jobs. Although growth in job postings for data scientists in the U.S. has slowed, the decline hasn’t been nearly as dramatic as that of other occupations. 

Moreover, within the finance and insurance industry, job postings for data scientists and analysts have actually increased since the COVID-19 pandemic started. Talk about job security!

4. You’ll make a good wage

As a data scientist, you can make well over six figures a year. 

That being said, the pay varies depending on things like location, skill level, experience, industry, and employer. As an entry-level data scientist, you can expect to make closer to $70,000 — still not bad! 

As a side note, data science also presents perfect freelancing opportunities. As long as you have a good internet connection and enough experience, there’s no reason why you can’t become a well-paid consultant to major firms around the world.

5. You can change the world

You really can change the world when working in the data science field. 

It’s not just about helping businesses make better, more profitable decisions. Data science is also being utilized for the greater good of society. For example, data science can help fight global warming and improve people’s lives in the developing world. 

Data science is also paramount in overcoming COVID-19. Without data science, we’d have no idea which factors slow the infection rate and which hasten it or how people are moving during travel restrictions. We’d also be stuck with inefficient contact tracing!
