12 Top most used analytical tools for Data Scientists with links to websites and courses.


Data Science has been a trending field of study in various industries in today’s era, because of the tremendous increase in data generation with high velocity. Soon every business sector started building new strategies to make huge profits from the data being generated. Here comes the role of data scientist who not only drives meaningful insights out of huge and complex data but also he/she should have the strong domain knowledge, should be flexible enough to use different tools as when needed and updated with skills to remain valuable assets to their organizations. To become a professional Data Scientist, you must have a strong hold on domain knowledge, statistics, programming, data interpretation, and communication skills.
