• Understand the Problem

A Data Scientist should learn about the issue at ground and ask the right questions.

• Collect Enough Data

As the name implies, a Data Scientist has to collect enough data in order to make sense of the problem at hand and get a better grip of the issue with respect to the time, money and resources needed.

• Process the Raw Data

Data can rarely be used in its original form. It needs to be processed, and there exist various methods to convert it into a usable format.

• Explore the Data

After the data has been processed and converted into a form that can then be used in the later stages, the Data Scientist need to explore it further so as to get the characteristics of the data and find out more about the obvious trends, correlation and more.

• Analyze the Data

This is where the magic happens. The Data Scientist deploys various arsenals in his repository like Machine Learning, statistics and probability, linear and logistic regression, time-series analysis and more in order to make sense of the data.

• Communicate the Results

At the end of the entire process, there is a need to communicate the findings to the right stakeholders in order to get the groundwork done for all recognized issues.
