5 Must-Have Skills to Become a Data Scientist

You might think of data scientists as having a technical, mathematical mind. Still, to perform this highly specialised role successfully, you need more than just expertise in programming, statistics, and statistical software.

A number of soft skills will assist you in doing your job well. This article will highlight five such skills that every data scientist should possess.

must have skills to become a data scientist

Strong Math Skills

No matter how many years you spend in school or how long you’ve been using the mathematical side of your brain, if you’re not strong at mathematical concepts, you’ll have a challenging time doing the technical side of data science. You need to be able to grasp and apply simple mathematical principles to problems. You might have learned about many of these skills in your data science course, but if you’re not using them regularly and applying them to your work, you’ll miss out on being a true data scientist.

These skills include:

Using mathematical operations and relationships to make sense of the data you’re studying

Familiarity with linear regression, non-linear regression, logistic regression and classification

Understanding fundamental time series analysis such as how to make trendlines and how to apply regression

Applying linear algebra to see how data is structured

Strong Programming Skills

Programming is the most important technical skill you need in data science. If you’re programming in something other than Java or Python (or even both), you’ll have much more trouble mastering data science. Without strong programming skills, you’ll find it difficult to do the things data scientists need to do, and you might also have difficulty finding a job in the field. You’ll need to learn to do the programming so that you can write algorithms to analyse data, and you’ll need to learn how to write tests, run tests, and get the data you need.

This is a skill you can develop over time, but you must start somewhere, which is why this article suggests learning how to code in Python first.

So you might ask yourself, what should I learn first: Python or another language?

Some argue that you should learn Python first because it is the most widely used language in data science. However, other language proponents argue that Python isn’t the best language for data science, so they recommend a language like R.

The main thing is to focus on what you want to do with data science, and if you’re aiming to learn a language that is specific to data science (e.g. Python) then go ahead and learn Python; otherwise, go for something that works more generally (e.g. R). The important thing is to choose a language that is easy for you to use, as this will make you more efficient.

In this case, we think it’s best to start with Python, as the use of R is relatively limited compared to Python. If you decide to learn R, you should know it as a complement to Python and learn Python first, as this will help you learn how to program in a language used for data science.

When you learn to program, you will be able to perform lots of tasks on your own. This is an extremely useful skill when you want to be a data scientist, as you’ll need to do lots of things yourself. Whether you learn to do these things in R or Python, the fact is that you’ll need to learn how to do them yourself. This is something you’ll have to do if you’re a true data scientist, so we’d suggest learning to the program before you attempt to apply for a data science job.

Visualisation Skills

The data scientist needs to be able to produce visualisations that present the information they’ve extracted from the data. In many cases, a data scientist will have created a spreadsheet before they get started on their analysis, which is why it’s important for you to be able to transform a spreadsheet into a visualisation. Visualisation can be the only way to communicate some of the data that you’ve extracted, and it can be a key element in determining your future success in the field.

To produce visualisations, you’ll need to be able to use a tool such as Tableau. Many other tools can be used to create visualisations, but they don’t necessarily have the ability to create a clear representation of the information you’re analysing.

In our opinion, you should learn to do visualisations with a tool like Tableau, as this is the tool you’ll need to use when you want to create these visualisations. To do this, you’ll need to learn to use Tableau, and you’ll learn to use Tableau as you learn how to program and do visualisations.

If you want to create visualisations as part of your data science job, then you should learn how to use Tableau. If you’re going to start applying for data science jobs, then you should try to produce visualisations as your first job, or at least your first job as a data scientist. By producing visualisations, you’ll have a clear idea of what you can do in the data science industry. You’ll also gain an insight into how data scientists work, as you must understand how to make visualisations.

Communication Skills

While we’re talking about soft skills, you’ll need to have good communication skills, because you’ll need to discuss your findings with your colleagues. You’ll need to get your results into shape, but you’ll also need to convince your colleagues that your results are correct. If you’re not good at convincing people of the data you’ve extracted, or the data that you’ve interpreted, then you’ll struggle to progress in the field.

While we understand that learning communication skills isn’t a trivial matter, we’d suggest that you can develop these skills by learning how to use an email client and then learning how to do basic email communication. Once you’ve done this, you’ll understand how communication works, making it easier to talk to your colleagues, and you’ll also have a good understanding of email communication.

It’s also important that you are able to write emails. This is particularly important when you want to get feedback on your work. Because your emails will be a representation of the data you’ve extracted, you’ll want to make sure that they’re accurate, and you’ll want to be careful with how you communicate.


You might be thinking that this is a strange skill to mention in this article, but we’re going to tell you why we think you should develop this skill: your desire to learn and explore the world of data science.

As we’ve already mentioned, data science is the study of data. This means that it’s important for you to be curious about the world of data science. By thinking about the world of data science, you’ll better understand the field, which is the essence of what makes a data scientist.

If you’re not curious about the data you’re analysing, then it’s unlikely that you’ll understand the problems in the data, which is exactly why it’s important for you to learn to be curious about data science. You’ll need to learn how to take it in, and you’ll need to learn how to take the data you’re studying and try to figure out what it means. By doing this, you’ll learn what a data scientist actually does.

By developing this skill, you’ll learn to look at data and understand it, which will help you get started on your data science career. When you are trying to explain to your colleagues the data you’ve extracted, you need to be able to do so in a way that makes sense. This skill of curiosity will help you do this.


Data scientists are the new rock stars of the modern world, but the job requires so much more than being a great coder. To succeed in data science, you need to learn to think mathematically and be strong in mathematics. The only way to learn these skills is by practising and by learning a programming language like Python.

After you have learnt to program, you can build your career in data science by learning more maths. You will need to know to understand data by learning to think mathematically. Visualisation skills will also help you when you’re analysing data. Finally, to succeed in data science, you’ll need to develop the desire to learn about the field. So, in summary, to succeed in data science, you need to learn how to think like a mathematician, you need to be strong in mathematics, you need to learn how to think about data, and you need to be curious.
