  • Knowledge of maths, computer science, and statistics. 
  • Working with big data, structured, unstructured, and semi-structured data. 
  • Understanding of programming languages like Python, R, Java, etc. 
  • Communication skills, teamwork, and presentation skills. 
  • Knowledge of Machine Learning and Deep learning. 
  • Skills like data visualization, data wrangling, data analyzing, etc. 
  • Understanding the business; its core, products or services, working system, motive, and future plans. 
  • Familiarities with collecting, processing, and storing data.

Career in Data Science

Data Science is one of the top career choices with many positions to offer. It is best suited for science and business professionals. A few data science jobs are listed below:

Data Scientists

Data Scientists are involved in studying data as well as business for an organization to use the information in decision-making. Generally, they ask questions to be answered, find future trends, and write algorithms for the system. 

Data Analysts

Data Analysts analyze the data to find answers for businesses. A huge part of their job is to perform different analyses of data, like predictive analysis, to find patterns. 

Data Engineer

Data Engineers work on the initial levels of data science departments. Their job is to collect data from various sources and convert raw data into information for data scientists to use.

Data Architect

Data Architects work on the infrastructure of a business or organization, to manage and store data in the system.


Statticians extract information from data clusters and develop new methods for engineers to apply in their process. 

Business Analysts

Business Analysts are directly involved in taking actions as per data insights and are responsible for business growth.

Data Science is a very large field that doesn’t stop here. To know more about data science and learn how to be a part of this world, watch this video:

What is Machine learning?

Machine Learning is a branch of Artificial Intelligence, which has vast use across different fields including data science. In data science, it extracts data and finds patterns using algorithms. It also develops different models to analyze data and predict future trends. For example, social media platforms use machine learning methods to understand customer behavior to suggest products, services, and other things available on social media to users. 

Skills required in Machine learning
