Seeing the volume of data being produced and the development of analytics, data science is now essential for businesses. Companies from many industries, including those in finance, marketing, retail, IT, and banking, are working to get the most out of their data. All of them are seeking data scientists. As a result of this demand, there is a significant need for data scientists everywhere in the world. It is a lucrative career for many because of the kind of income that a corporation can offer and IBM's declaration that it is a trending job of the 21st century. Any individual from any background can pursue a career as a data scientist in this fieldKeeping the high demand and trends in mind, we've come up with a guide that will cover important topics like skills for data scientists, data scientist job descriptions, the scope of data science, and much more. Let's begin with the basics of what is data science and what is data scientist. 

What Is Data Science?

In the vast subject of "data science," useful insights and hidden knowledge can be reviewed, analyzed, and extracted from raw data using various procedures, ideas, tools, and technologies.

Data scientists are technical professionals in data analysis who can solve difficult issues. They gather, examine, and evaluate vast amounts of data while working with a variety of computer science, statistics, and mathematics-related concepts. They are in charge of offering perspectives outside of statistical analyses.

With this, let's proceed to look into data scientist roles and responsibilities which is basically the data scientist job description.

Data Scientist Roles and Responsibilities: What Does a Data Scientist Do?   

If we've to sum up the roles and responsibilities of a data scientist in a short way, it will include three basic steps. However, each type of data science project that  received is different and requires different types of work, but, the common few responsibilities are: 

Collection Of Data 

Data scientists have to work with data all the time. There's no work for data scientists in the unavailability of data. So the first and most important step is data collection. There are various tools available for data scientists to collect the data. So, the data scientists need to get familiar with these tools. Some of these tools are ETL, cloud integration tools, etc. 

Data Transformation 

Data scientists then proceed to alter the data after acquiring it. For the system to function effectively during the analysis phase, this transformation involves changing the form and arrangement of the raw data.


Data scientists employ data-driven methodologies to address business-related issues once they have the data at hand. For example, suppose the organization wants to introduce a new product. Based on customer research and data, data scientists can predict the success of these new products/services. 

Reporting The Data 

The last stage is to communicate the important conclusions drawn from the data. The difficulty in disseminating and consuming reports that may have an impact on the understanding of results presents a barrier for data scientists in this situation. The reports cannot support analysis of sensitivity or interactive validation without knowing how the supplied data was modified.

With these being the important responsibilities of a data scientist, let's see the skills required for data scientist.

Data Scientist Skills Required 

Like any other profession, the data science field also requires a bunch of skills. Let's see what data scientist skills required. The skills are often categorized as technical and non-technical skills based on data scientist qualifications. Let's see them: 

Programming Languages 

The most basic necessity for any data scientist is to have basic knowledge of programming languages. Even if you're a beginner, the recruiter of any company will expect you to have sound knowledge of certain programming languages like Python and R. This might sound funny to you but Python & R are considered king and queen of data science. They are perfect for beginners and even very easy to learn. 

Math & Statistics Skills 

Although you don't need any prior knowledge of mathematics to begin learning data science, you won't advance in your career if you don't become familiar with some basic statistical and mathematical ideas. 

Building solid data models, selecting and utilizing the various data methodologies accessible, and correctly comprehending the data you are working with all require a solid understanding of statistics. 

Data Visualization 

Next, an important technical skill for data science roles is data visualization. The skill involves the ability to transform textual data in the creative form of graphs and charts. This is done to make the understanding process easier for stakeholders and people who decide on the organization. 

Let's see what are some of the non-technical skills: 

Ethically Working With Data 

Data scientists should have an ethical consciousness to guarantee that data has beneficial effects. Developing fair, transparent, and responsible algorithms requires familiarising oneself with key ideas like data privacy, algorithm bias, and feedback loops. 


Being a data scientist requires problem-solving aptitude and motivation. Data science is all about achieving that. But to solve a problem effectively, one must have both the ability and the desire to delve deep into the cause of the problem. The top problem solvers can swiftly pinpoint challenging problems that are often disguised before fast shifting to the best approaches for handling them.

Communication Skill

Companies wanting to hire a competent data scientist want someone who can communicate their technical findings to a non-technical team, such as the marketing or sales departments, effectively and fluently. In addition to providing the business with quantitative insights and understanding the needs of their non-technical colleagues to effectively handle the data, a data scientist must empower the business to make decisions.

Now, if you're wondering how to be a data scientist or what are data scientist qualifications, no need to worry, as the next part will help you to answer these questions for you. 

How To Become A Data Scientist

Below mentioned is a step-by-step guide, every aspiring data scientist can follow.  

Step1: Basic Preparation 

Before spending and investing in online courses, or master's degrees, you must get familiar with the in and out of the field. Research and get to know who is a data scientist, what are the skills required to become one, what are the responsibilities of a data scientist, etc. One can also start the basic preparation like learning about programming languages, learning math, statistics, etc. 

Step2: Get Undergraduate 

The minimum educational qualification required for a data scientist is an undergraduate degree. If you've not completed your undergraduate degree yet, consider completing it with technical skills. By making connections within academic groups, searching for internship possibilities, and seeking advice from instructors and advisers, now is the perfect moment to begin establishing professional networks.

Step3: Invest To Learn The Skill
