What is Data Science?
Data science combines the knowledge of programming, mathematics, and statistics to extract meaningful insights from data using scientific methods, algorithms, processes, and systems to extract knowledge from data.
What do data scientists do?
The job of a data scientist is to examine and research where to fetch or extract answers to questions from related and available data.
They also source for, manage, and analyze large amounts of unstructured data and structure it into useful and presentable data, and also secure data from varied sources.
