Statisticians are professional who applies statistical or mathematical methods to real-world problems. They are concerned with collecting, analysing, interpreting, and presenting data to help make business decisions.

They are in demand across various industries because businesses realizes how valuable data-driven decision-making is. Statisticians collect the data through surveys, experiments or opinion polls. However, statistician uses sample data for analysis rather than whole (population) data.

Sometimes statisticians are clubbed with data scientists, but their roles differ. As a statistician, you have to design experiments, conduct and develop surveys, and create estimates. In contrast, as a data scientist, you have to find the problem statement, create a process for the problem and present the result to the stakeholders.

In this article, we will discuss the roles and responsibilities of statistician, what skills should statistician have, how to become a statistician in India, top institutes that offers statistics in India.

• Train assistants and other members of the team on how to properly organize findings and read data collected.
• Prepare detailed reports for management and other departments by analyzing and interpreting data.
• Define and utilize statistical methods to solve industry-specific problems in fields such as economics and engineering.
• Compare and analyze provided statistical information to identify patterns, relationships and problems.
• Apply sampling techniques to determine and define ideal categories to be questioned effectively.

## What skills should a Statistician have?

To be a successful statistician, you must have advanced technical, communication and leadership skills.
