In this course you will get an introduction to the main tools and ideas which are required for Data Scientist/Business Analyst/Data Analyst/Analytics Manager/Actuarial Scientist/Business Analytic Practitioners. The course gives an overview of the data, questions, and tools that data analysts and data scientists work with. The course is a combination of various data science concepts such as machine learning, visualization, data mining, programming, data mugging, etc. There are three components to this course. The first is a conceptual introduction to the ideas behind turning data into actionable knowledge. The second is manual calculations will be shown on how formulae’s are used behind the logics. The third is a practical introduction to the tools that will be used in the program like R/Python Programming and EXCEL.

A report by AIM had found out that the average salary for a data scientist in India is ₹12.7 lakh per annum in 2018. However, this trend has levelled off with the average analytics salary capped at ₹12.6 lakh per annum across all experience levels in 2019. In fact, Data Analytics professionals are currently benefitting from the big data wave with analytics professionals earning 26% higher than an average software engineer in India.

Data analysts dissect data to tell a story. Data scientists have the same skills as data analysts, but they also have a strong foundation in modeling, statistics, analytics and computer science. Unlike data analysts, they typically have machine learning skills.

The two most commonly used languages required for gaining expertise in Data Science are Python and R. These languages are used for statistical analysis or ML projects. R is an open-source language used for statistical computing and graphics, while Python is a more preferred language for Data Science as it is faster as compared to R.
