In recent years, the median salary for people who work in data science has gone up a lot. This growth is mostly due to the fact that more and more industries need data science experts to unlock the potential of the data they already have. As a result, the rise in demand for qualified data scientists was a big reason why the median salary went up overall.

The median salary of a data scientist in the USA is 146,000 USD per year.
In the US, a data scientist's salary can go up by about 12% every 17 months.
A data scientist who is just starting out can make up to $94,600 per year.
The average salary for a data scientist with two to five years of experience is $116,000. This is 23% more than the starting salary for a data scientist.

Companies can use Data Science to rapidly and reliably analyse vast volumes of data from many sources to get useful insights for making better decisions. Data science has numerous potential applications, including but not limited to those in marketing, healthcare, banking, finance, government, and many more.

When you've gotten good at data science and have a lot of experience, you can move into related fields like marketing and sales, data quality, finance, and business intelligence, or even work as a consultant for a data-heavy industry leader.

You will learn how to use data analytics to manage and evaluate large and complicated datasets, as well as to find problems and offer solutions.
Data analytics, which is the process of collecting and organising data for analysis and prediction, is important for making important business decisions and putting in place needed changes.
A person who takes this Data Science Training course will learn how to extract data in different ways that could help their employer succeed.
