8 Must-Have Skills Of A Data Scientist

Whatever your background or skills, there are options for pursuing a career in data science. As the demand for data scientists continues to grow, the field offers students and professionals a highly attractive career path.

Many people out there are not data scientists but are interested in data and data science and want to know what kind of skills they need to work in this specific industry.

If you’re one of them, you have come to the right place. This article will tackle both technical and nontechnical skill requirements required for you to land a job as a data scientist. 

Working closely with your company, you’ll create solutions that better your company’s decision-making by effectively identifying issues and using data.

You’ll also be tasked with designing experiments, developing algorithms, and managing and extracting data to support other departments, customers, and the organization as a whole. 

Before you submit your resume, check out some data analyst resume LinkedIn tips and become familiar with the following attributes and skills required for your future job: 

1. Machine Learning And Deep Learning

In the sense that its name suggests, machine learning refers to the process of creating intelligent machines that can think, assess situations, and come up with solutions.

Using machine learning to craft precise models, an organization stands a better chance of identifying profit-generating opportunities and avoiding risks. Having hands-on knowledge of many types of algorithms is essential. 

Machine learning has taken to a new level with Deep Learning. Brain cells are the inspiration for the design. Simulating the human brain is the aim of this system.

Here, the Deep Neural Network is built with Artificial Neurons on a large scale. Many companies ask for knowledge of Deep Learning, so be educated and familiar with this.

Among machine learning experts, Python is the most preferred language, and TensorFlow is the most famous Python library for developing Deep Learning models. 

2. Business Acuity 

You need to understand your industry and your organization’s problems to succeed as a data scientist.

When it comes to data science, you need to identify which issues need to be fixed for the company to thrive and how to implement new strategies to help the business make the most of its data.

Data scientists must understand how the company functions to do this effectively. Even if you’re not assigned to business departments, acquiring business skills will still make you a better candidate than others.  

3. Statistics 

Being a data scientist requires a solid understanding of statistics. The statistical studies, distributions, maximum likelihood estimations, and others should be familiar to you.

Machine learning is no exception, but one of the most critical elements of your statistics knowledge will be determining when specific techniques are possible or impossible.

At all types of firms, statistics is essential. Particularly at data-driven firms, your insights will be relied upon by stakeholders making decisions and assessing outcomes of experiments. 

4. Data Visualization 

The Data Visualization aspect of machine learning is one of the most fun parts, as it’s more an art form than a step in the hardwired journey.

A universal approach is impractical here. Experts in Data Visualization know what to do with their visualizations so that they tell an engaging story. 

There are different vital types of data analysis methods and techniques. Begin by familiarizing yourself with plots like a histogram, a bar chart, a pie chart, and continue with advanced charts such as waterfall charts, thermometer charts, and so on.

Exploratory data analysis can benefit from plots like these. Understanding univariate and bivariate analyses becomes much easier when displayed in colored charts.

In case you wonder which tools are used during this step, don’t let your worries go to your head. Different languages all offer a range of libraries for the creation of advanced charts.

5. Great Data Intuition 

This skill is perhaps the essential nontechnical skill a data scientist can possess.

A data scientist with intuition and experience can spot insights within large data sets that aren’t always apparent. A data scientist with the proper training should be able to become more proficient in this field.

These specific data scientist skills are not taught in schools, so they need to be polished and acquired through experience and, perhaps, self-learning.   

6. Programming Knowledge 


The increase in computing power is primarily responsible for the rise of machine learning. Communication with machines can only be accomplished through programming.

Does it matter if you’re the best programmer? Well, technically, no. However, you must be knowledgeable and comfortable to perform it occasionally. 

Choosing a programming language is the first step. A few examples include Python, R, and Julia. Julia is a general-purpose programming language with rapid prototyping and multiple data science libraries provided by Python. Julia is faster and is more suited for data science. 

7. Communication Skills 

In the quest for data scientists, companies need individuals who can communicate their technical assumptions to staff who belong to diverse departments, including those working in sales and marketing.

As a data scientist, you should speak to people from all different backgrounds as this could lead to stronger relationships and higher productivity.

The data scientist must also use data storytelling to communicate findings to the business. Telling your story correctly and consistently will ensure everyone on your team understands your company’s situation and everything in relation to it. 

8. Calculus And Algebra 

Understanding these concepts is most crucial for companies wherein their products are launched and defined by their data. Many companies find that small changes in algorithm optimization or predictive performance can be a huge success.

During an interview for a data science position, you may be asked to demonstrate your ability to deduce the machine learning and statistics results from other sources.

Many of these techniques are based on introductory linear algebra or multivariable calculus, so your interviewer may ask you some questions in these areas.

If many Python or R implementations are out of the box, why would a data scientist need to learn this? The answer is that a data science team can build out the performances themselves at some point, which can be crucial for development. 


You’ll have a pretty long journey to become a data scientist. It could be challenging to find time to learn and update your technical skills constantly. It’s time to advance your data analytics and data science skills to acquire your dream job position finally.
