In this article, we will delve deep into – what is data science, what a data scientist is capable of, and what is data science course and its scope. Let’s start with understanding the concept of data science and a peek into what a data scientist does.

What is Data Science?

Data science is summarized by data gathering, analysis, and interpretation, among others. It is a field of study that combines mathematical and statistical methods to collect and interpret data, which then can be used to solve business problems. Many companies use data science for-

  • Better decision making
  • Predictive analysis
  • Discovering patterns in data

Data science is used in many industries, namely, banking, healthcare, manufacturing, marketing, sales, and others. Since many organizations are finding it difficult to manage the enormous amount of data, the need for talented data scientists is on the rise. The ability of data scientists to turn a sea of data into actionable insight is what makes data scientists an inevitable part of the business organization in the current milieu. Before we delve deep into what data scientists do, let’s understand who data scientist is and what are their roles and responsibilities in an organization.

Who is a Data Scientist?

A person who collects, analyses, and interprets data is the apt answer to what is meaning of a data scientist. However, a data scientist’s job scope extends to more than just data collection and interpretation. They work with different departments to understand business goals and fulfil them by deploying their mathematics and statistics knowledge. Data scientists also play an important role in many business decisions. Besides data science and data analytics, data scientists also undertake these activities:

  • Designing data modelling process
  • Developing algorithms and predictive models for data collecting
  • Share data with different departments to ensure the smooth functioning of business

A data scientist performs a varied set of roles and responsibilities with each project. Below, we have stated some common roles and responsibilities of data scientists.

What is the Role of a Data Scientist in an Organization?

  1. Deploying their skills to undertake data mining activity to extract usable data from different sources.
  2. Collecting data from different sources and carrying out activities like- data sampling, data cleaning, data integration, data storage, etc.
  3. Analyzing collected data and presenting it in a manner that is easy to understand and take action on.
  4. Collaborating with different departments to find strategic solutions to business problems through scientific tools.
  5. Continuously performing the data collection and other steps to find solutions to new problems.

A data scientist must perform these roles and responsibilities daily in a business organization. In fact, this is what a data scientist does to make a splash in the field.

What Are the Qualifications Required for Becoming a Successful Data Scientist?

Most employers are looking for data scientists with advanced degrees, such as a Masters in data science or a similar field. So, aspiring candidates should have a bachelor’s or master’s degree in data science, mathematics, statistics, or similar fields.

However, if you don’t want to take up a full-time course but want to build an exhilarating career in data science, you can take up one of the data science certification courses to enhance your skillset and knowledge. Emeritus offers various data science certification courses in collaboration with reputed institutes.

What Skills Are Required for Becoming a Data Scientist?

Statistical analysis

Statistical analysis is an important function of a data scientist’s job profile. Therefore, an aspiring candidate should be well-versed in different statistical analysis processes and techniques to succeed in the job. They must also be prolific at identifying patterns in data and making sense of the pattern.

Machine learning

Machine learning is an active part of several marketing campaigns. However, the novel concept is slowly gaining momentum in the Indian commercial sector. As a data scientist, one must align machine learning techniques to business goals and objectives successfully. You must also be skilled in implementing algorithms and statistical models into the computer to transmit and extract data automatically.

Computer science

Many mathematical calculations and statical projections have been made easy by computer systems. Therefore, a data scientist must be well-versed in the principle of the computer system. In addition to this, they should be well-equipped with the fundamentals of artificial intelligence, database systems, numerical analysis, and software engineering, among others.


A data scientist must be skilled to use computer coding languages like C, C++, Java, Python, and R because these languages aid the data analysis process. For example, computer languages like Python and R are widely used to interpret data in interaction graphs and pie charts and make data accessible and understandable to a layman.

Data storytelling

Data scientists often interact with stakeholders and department heads to present data. Hence, they must be good storytellers to make non-technical audiences comprehend data analysis.

What to Study for Attracting the Right Data Scientist Job Opportunities?

Most organizations seek data scientists with advanced degrees in data science and similar fields while recruiting. Therefore, to attract the right job opportunities, you can undertake a data science certificate course. Such a course makes you well-versed with the nitty-gritty about data science and other related aspects, helping you attain knowledge, hone skills, and gain a deeper insight into what a data scientist does.

Emeritus India offers various data science courses that help you in advancing career and grab the right work opportunities. However, as what data science course to study is solely an aspiring candidate’s decision, choose wisely.
