Data Scientist vs Data Analyst

A data analyst may spend more time on routine analysis, providing reports regularly. A data scientist may design the way data is stored, manipulated and analyzed. Simply put, a data analyst makes sense out of existing data, whereas a data scientist works on new ways of capturing and analyzing data to be used by the analysts.

If you love numbers and statistics as well as computer programming, either path could be a good fit for your career goals.
