How to Learn Data Science in 2022 (the Right Way)

learn-data-science

Demand for data scientists is at an all-time high. If you’re considering a career in data science, now’s a great time to enter the field. 

However, the unfortunate reality is that most people who try to learn data science fail. They fail because their method is filled with flaws that sabotage their progress. Don’t worry: failure is 100% avoidable. 

The key to learning data science quickly and effectively is finding the right approach.

This article will show 5 reasons why most learning methods cause people to fail. I’ll unveil the correct way to learn, which I discovered 10 years ago, after transitioning from a history teacher to a machine learning engineer.

Why do most data science learners fail?

High barriers to entry

Many would-be data science learners give up because they think learning data science is too expensive. Bootcamps and certification programs can come with huge price tags that scare people off. Many learners don’t realize there are more affordable ways to learn.  

Boring curriculum

Affordable courses don’t guarantee success. Many online courses consist of dry video lectures or recordings of other people writing code. This isn’t engaging, so learners end up tuning out. 

As a result, these types of courses have completion rates of 5% to 15%. Not great odds. 

Life gets in the way

Many data science courses have rigid schedules. Courses begin in a particular week, end in another, and may require live sessions at specific times. 

People who are learning online often have jobs, families, or other obligations. That can make keeping up with those schedules a challenge. 

The difficulty curve is off

If courses are too easy or too hard, most learners will eventually fall off the wagon. One common problem in online data science programs is that they’ve been built with pre-existing courses stuck together. One course might seem too easy, but the next is too hard. This happens because these courses weren’t built together.

Lessons don’t feel relevant

People tend to stick with their studies when they feel like they’re making progress toward their goals. But many data science courses are focused on lectures and drills, rather than doing real-world data science work. This can leave learners feeling like they are treading water. 

The right way to learn data science

Before I founded Dataquest, I taught myself the skills required to go from working in a non-technical job to working as a machine learning engineer

Through that experience — and through the experiences of the hundreds of thousands of learners who’ve gained data science skills on Dataquest over the last eight years — I’ve come to understand a lot about what works and what doesn’t when it comes to learning data science. 

And it’s all built into the Dataquest experience. 

Dataquest’s “learning loop”

For learners to be successful, we need to feel like we’re making progress. The importance of this can’t be understated. We need to feel like we can immediately use the skills we’re learning.

That’s why Dataquest is hands-on. You’ll be writing and running real code and working with real datasets from day one. 

In our side-by-side learning platform, you’ll read about a concept on the left side of the screen, then be challenged to write and run real code to apply what you’ve learned on the right side. 

This simple learning loop repeats through every single one of our courses. You learn something new and immediately apply it to a real data science problem. Each screen builds on the previous screen and leads into the next one.

That means that as you’re learning, you’ll know you have truly grasped the material because you’re using it to do real data science work. 

You’re not watching lectures. You’re not filling in the blanks or answering multiple choice questions. You’re writing and running code, exactly like you will in a real data science job. 

Tailored course paths

An important part of this approach is that our courses are carefully sequenced to ensure there are no gaps. One course always leads into the next one, and each has a very specific goal in mind.

For example, here are some of our career paths:

Many of our students love these paths because they contain everything  they need to know to obtain a position. Yeah, really! If you want to become a data analyst, every ounce of information you need is within the Data Analyst career path.

Plus, there are no prerequisites. Anybody can do it!

Fun real-world projects 

While all of our courses get you working hands-on with real data, we also know that it’s critical to synthesize the skills as you learn.

That’s why most of our courses end with guided projects that challenge you to answer real data science questions using the skills you’ve learned in previous courses. 

These projects are fun learning tools that help cement your new knowledge, but they’ll also help you when it’s time for your job search, as you can include them in your project portfolio. (Hiring managers love it when you do this, by the way.)

Example projects in the data science path include: 

Why it works: real success stories

This approach worked for me, and it’s working for Dataquest students too!

You don’t have to take my word for it, though. Here’s what some recent learners have to say about their Dataquest experience:

Dilara, Data Scientist at Perfist: “After I completed my Dataquest courses, I decided I should start looking for a job or an internship. I was hired as a data science trainee in **ten days**, and got promoted in four months.”

Rahila, Technical Data Scientist at Clinfocus: “Dataquest definitely won my heart with the in-browser coding experience. I had come across so many platforms and tried the free coding experience with others, but Dataquest […] was a better way to learn.”

Viktoria, Data Scientist at Fractal Analytics: “Things like statistics and programming are not easy to learn. But Dataquest explains them more clearly than all other resources [and is] understandable even for a person without specialized education.”

And you don’t have to take their word for it, either! Dataquest is free to start, so dive in, start learning,, and see how the Dataquest difference can help you.
