Data Science in Brief

The evolution of data analysis, big data, and mathematical statistics has led to the emergence of data science. Notably, data science is a branch of study which uses several scientific algorithms, processes, and methods to extract insights from a wide array of data.

It analyses raw data and helps find hidden patterns in it. Data science is primarily used to make predictions and decisions based on prescriptive analytics, Machine Learning (ML), and predictive casual analytics. 

It is best to read some data science books to get a better understanding of data science.

Why Data Science?

There are several reasons why data science has become a new trend in the market and is providing one of the hottest jobs of the 21st century. And, some of them are as follows:

1. Increased Demand: Data science has grown to provide one of the most in-demand jobs in the market. Every company, whether big or small, has learned now that it needs a data scientist to keep up with the industry and is looking for professional, qualified employees who can handle and manage its data.

According to statistics, this demand is only going to increase as there is still a dire shortage of data science professionals. This situation makes it very easy for graduates to land a job as a data scientist if they have the desired skills and required qualifications.

2. High Salary: The unbeaten salaries of data scientists are one of the most important factors that make it a desirable job for young professionals and graduates. The average annual pay of a data scientist in India is Rs 882,895, whereas the same in the U.S. is $96,501. The salary of a data scientist is much higher compared to other jobs and it is one of the highest-paid fields to get into.

3. Ever-evolving Field: Data science is evolving in all fields, from retail to medicine, education to transportation and health care to IT, every small or big business is now using data science for better production value and increased profits. Data scientists have thus become the trusted advisers and strategic partners to their companies as data is the most valuable asset that businesses now have.
