Frequently Asked Questions

What is Data Science?

Data Science is a combination of various tools, algorithms, and machine learning principles with the goal to discover hidden patterns from the raw data. This raw data is further analysed and used to make decisions and predictions making use of predictive causal analytics, prescriptive analytics, machine learning patterns for discovery, etc. These responsibilities of analysing the data is carried out by the Data Scientist who work with statisticians and mathematicians to crack the complex data problems.
