Data Science is the process in which a data scientist analysis the complete data of a company and finds a way to unlock all the data through data inference, algorithm development, and technology and other techniques.

Basically, the data scientist identifies the data analysis issues and figure out greater opportunities for the company and a lot more. To become a data scientist you’ve to learn data science from online or office instructions. who offer the best online data science courses at an affordable budget with certification.

According to IBM statement , the demand of a Data Scientist has been increased to 28 % from the last 2 years.

The proper job of a data scientist is given below in point-to-point analysis.

- Collect all the structured and unstructured data in the right set.
- Analysis of all the data and figure out how can this data be compromised.
- Figure out the patterns and trends of the data of organizations.
- Cleaning the data to increase the space and accuracy of data in the right way.
- Any other relevant point of a data scientist.

In simple words, The Data Scientist is someone who knows how to interpret data using different types of methods, statistics and machine learning. It took a lot of time to collect data and analysis and find out. How can this data be modified that offers great opportunities to the organization?

This is the most important point of all the conversation. Data scientist’s average salary is defined by the University of Wisconsin as $95,000. The median salary of a data scientist is $128,800 and if the data scientist is in the managerial role the salary will be $185,000.

So the data scientist starting salary will be approx $95,000 to 120,000.
