What is a Data Scientist? A Complete Guide

As the demand for data scientists increases, you may be wondering what is “data scientist”. In this article, I’ll explain what it is and how to become one.

What is a data scientist?

Data scientists are professionals who use data to solve problems. They are not just analysts, they are problem-solvers who use data to make decisions. They are tasked with analyzing and interpreting large amounts of data to make actionable predictions. This data can come from a variety of sources including log files, web traffic, sensor data and social media posts.

Data Scientists work closely with data analysts as well as data engineers, product managers, researchers, and other professionals across an organization to develop insights into customer needs, market trends, or any other aspect of their business that requires analysis and insight.”

Responsibilities of a Data Scientist

Data Scientists are analytical thinkers who thrive on figuring out how to get answers from seemingly unstructured data. Data scientists have strong programming skills, knowledge of data management and analytics tools like SQL, SAS and R. They are also comfortable working with large scale databases and servers that store information

The responsibilities of a data scientist include:

  • Collecting, analyzing and interpreting data – A data scientist’s job is to collect, analyze and interpret the information from their company’s databases. They use this information to solve problems by finding patterns in the collected data.
  • Creating models that help businesses make better decisions based on their analysis of past trends or events that have happened in the past such as sales.
  • Communicating results – Data scientists use their skills to address the many data-related problems that can arise in fields such as business, science, technology and medicine.

Hard and Soft Skills Required to Become a Data Scientist

The skills required for a data scientist vary depending on the project they are working on. Some projects require a deep understanding of statistics while others may require more technical skills such as machine learning or artificial intelligence programming languages.

Two main skills make a data scientist:

i) Soft Skills

These include;

  • Interpersonal Skills – Data scientists must have strong interpersonal skills to work with people from all walks of life who have different views on issues.
  • Problem-Solving Skills – Data scientist needs problem-solving skills because they will often be asked to solve problems that require them to make decisions based on incomplete information or no information at all.
  • Communication skills – A good data scientist must be able to communicate their findings with their colleagues in the team, clients and other stakeholders and make them understand the value proposition of the research.
  • Analytical thinking skills – Good data scientists think about how best to collect information from various sources, analyze it and use it to solve business problems or make decisions based on this information.

ii) Hard Skills

Data scientists also need to have a deep understanding of how their tools work, which includes proficiency with programming languages such as Python or R. They need to be able to write their code if they don’t already have experience doing so.

If you don’t have these skills, you will need to acquire them before you start working as a data scientist.

How to Become a Data Scientist

Data scientist

Data science is a career that allows you to use your creativity and analytical skills to solve complex problems. This is what makes data science so attractive to employers, as well as to people who are looking for a career with more meaning.

But how do you become a data scientist? There are no specific training courses that teach people how to become data scientists. In general, it requires a combination of education, experience, and skills. For example, if you want to work in the field of medical research, you need to have a good understanding of statistics and programming languages. However, if you want to work on projects related to business decision-making or financial analysis, then you will probably need technical skills such as SQL and Python.

In addition, there are many different paths for individuals interested in becoming data scientists:

1) Those who have already had some practical experience working with data can find employment in several areas such as marketing or finance where they can use their skills for analyzing large amounts of information about customers or potential clients.

2) Those who already have degrees in mathematics or computer science may be able to advance their careers by developing new algorithms or modeling techniques.

3) Those who are passionate about mathematics can take courses at universities.


Data scientists must have an in-depth understanding of statistics and programming languages like R or Python. They must be able to communicate effectively with other people within their organization about how to solve problems using predictive models or machine learning algorithms.
