“Data science” is an umbrella term. While it is a career path, there are multiple different “branches” that you might want to choose, depending on your skills and preferences. If we were to define the term itself, data science is concerned with the gathering and analysis of huge chunks of data. These types of scientists usually work in huge corporations that handle vast amounts of data every single day - data scientists are responsible for the “translation” of the incoming data (numbers) into understandable, everyday English.

There are two popular branches of data science that a person looking at how to become a data scientist should know - data analytics and data engineering. Data analysts interpret the data that is presented in front of them and then bring the results back to their employers. Data engineers do the same thing - however, they must also gather the data AND, after they finish analyzing it, come up with a “plan of action” that would be based on the results of their interpretation.

Needless to say, this is a super TL;DR version of the data scientist career path, but you should be able to develop a general idea.

Why Become a Data Scientist?

Even though every single person that wants to get into the field of data science has their reason to do so, some general things could, quite possibly, apply to everyone. First of all, data scientist career path is quite stable with plenty of opportunities to grow and further develop your skills. This is a super important feature for most people out there - if you’re looking for a stable job, you probably want to dedicate yourself to it long-term, and also have an opportunity to keep on learning and growing in the field that you specialize in.

Another huge reason why people look into how to become a data scientist is the salary. There’s a huge amount of people that want to know how to become a data scientist simply because they want to earn the salary of one.

Glassdoor.com estimates that the average annual salary that a data scientist can expect to earn should revolve around the $113,300 mark. This would come out to almost $9442 per month! That’s an amazing salary!

Naturally, the salary that you might make as a data scientist will vary. It all depends on the specific career branch that you might choose, your experience and skill level with data science in general, your geographic residence, an so on. Having said that, it is quite evident that the data scientist's salary is something worth working towards!

What Do You Need to Be a Data Scientist?

When you’re looking for information on how to become a data scientist, there are three main things you need to keep in mind - education, learning path, and experience. If all three of them are in place, you can be certain that you’re on the right path of becoming a data scientist. With that said, let’s take a closer look at each of these points.

Data Scientist Education Requirements

Proper education is probably one of the most important points when you’re thinking about the data scientist career path. And this doesn’t necessarily only concern traditional education, either as you can learn how to become a data scientist without a degree! More and more people every single year are moving away from traditional, formal education institutions and are choosing to learn online. Whether that’s a good or a bad thing is still unknown, but one thing’s for certain - employers now are much more fluid in hiring people that don’t possess any form of traditional education but have acquired their knowledge in some other way. Online courses on platforms like DataCamp and Udacity, articles, tutorials, YouTube videos - the list goes on forever!

The best thing is, most of these online resources are free or low priced. And, even if it so happens, that you have some financial difficulties right now, you can find scholarships for online courses to help you take care of that! Take a look at this tutorial that explains how these small scholarships work.

Whatever your choice of receiving proper education on how to become a data scientist might be, it is still important to have one. The very first thing that you need to do is make sure that such fields like math, computer science and IT, in general, are “in-line” with your hobbies and interests. As a data scientist, you will spend a lot of time working on and with various amounts of technical data and numbers - better make sure that it’s your cup of tea!

Table: Pros and cons of DataCamp VS Udacity

After that’s all said and done, your best bet is to enroll in a field that would be closely related to data science - a bachelor's and master's degree in computer science, physics, maths or any other similar field will do fine. Now, this is probably more of a “motivation-based” point, but do keep in mind that you have to display good results from the very beginning of your studies to be able to score the data scientist career path. It’s a difficult profession that requires a lot of concentration and doesn’t have a lot of space for error - if you work hard from day one of your studies, you’ll increase your chance of actually getting the job afterward, and becoming a true professional in the field.
