Why Is Data Science The Best Career Option After 12th?

Building a career and earning. Money is the basic rule of society that every student has to follow to live a livelihood and engage in any activity that contributes towards the smooth functioning of society. Especially when a student enters his school life because it is the beginning phase of the career-building process. 

One by one he will clarify all the classes and finally, after 12-15 years, a student qualifies the 12th standard and takes a step on the platform where there are thousands of runways. Each runway brings the student towards a distinct career or profession. The student is required to choose something in which he is interested or capable to perform adequately and is a demanding one. 

There are thousands of career options after the 12th like a doctor, engineer, lawyer, researcher, etc. Before choosing any career a student needs to make sure whether the profession has demand in society or not. High demand will lead to more revenue and prosperity. One of the most demanding careers after 12th is becoming a Data Scientist. Now, Who is a Data Scientist, and How to become a data scientist after 12th? We will cover all such questions in this article. 

Who is a Data Scientist? 

A data scientist is more like a researcher who will analyse the data for actionable insights. A data scientist is hired by different organisations and corporations where he will analyse things that will offer great opportunities and help in positive growth. They will also validate the data to ensure the precision and smooth functioning of the organisation. 

Almost every multinational has a team of data scientists Google has a team of data scientists who will research and study the behaviour of the users or their problems and try to find out the most adequate solution for all their problems. All over a data scientist is a must for an organisation to grow without any hurdles. 

There are a few skills that are required to become a data scientist, this includes you must have prior knowledge of mathematics, data research, and analysis. A creative mind and natural curiosity is another most important factor required to become a professional data scientist. 

In simple language, a data scientist is a person who will implement scientific methods, techniques, and other processes to analyse data and make decisions based on outcomes and parameters obtained after research. A data scientist will allow the organisation to make reasonable decisions based on the research conducted by him. 

What does a data Scientist do?

There are a lot of things a data scientist needs to handle in the organisation. The main task is to figure out the questions and their reasonable answers only by using the data obtained. Some of the daily tasks that are performed by a data scientist are mentioned below, let’s have a look: 

  • Discuss the growth recommendations with the senior staff and help them as well. 
  • Uncover the insights using data patterns and major similarities in the sets of data. 
  • Look for innovative plans and their reliable execution. 
  • Integrate the machinery to improve the quality of products offered by the organisation. 
  • Develop the possible outcomes using data models and algorithms. 
  • Not only ordinary data research but also they need to prepare tools using Python, R, SAS, or SQL to briefly analyse the data. 

Hope so, that it is clear to you what are the major functions and operations needed to be accomplished as a data scientist. Now, there is a similar profession: Data analysis. Many students face difficulty in determining who is a Data Scientist and who is a Data analyst. To make it easy for you to understand them we have prepared the major differences between the Data Scientist and Data Analyst. 

What Is The Difference Between A Data Scientist And Data Analyst?

Both the data scientist and data analyst have similar operations to find out the trends in the data that will allow the organisation to take decisions to support positive growth. But when it comes to responsibility, a data scientist is more responsible and senior than a data analyst. A team of data analysts works under the data scientist. 

In simple language, the major work of data analysts is to analyze the data and submit the report to the data scientist. Now the major research and further analysis are performed by the data scientist. Data scientists need to form their questions while researching whereas data analysis has a predetermined mindset while working. 

Salary of data scientist 

The demand for Data scientists is very high in the industry. Almost every big organisation and multinationals require a team of data scientists and data researchers to make decisions. There are various factors that will determine the salary of a data scientist. This includes the demand and availability of data scientists in the market, qualifications, skills, experience, and many more. 

On average the beginning package of a data scientist starts from 5-50 LPA. This can be less or more depending upon the organisation. Some organisations offer more to their team of data scientists while others offer even less. Now, lets us move towards our main question, i.e. How to become a data scientist after 12th?
