###### Course Overview

## What is Analytics?

Analytics is the process of transforming converting data into insight for making better decisions. Business analytics is comprised of solutions which can be used to build analysis models and predict future business states. Business analytics can be focussed on internal or external processes. Business analytics involves the use of statistical techniques, information system software and operation research methodologies to explore the trends in data. There are different type of analytics which could be of great help to organizations.

## What is R?

R serves as an alternative to traditional SPSS and SAS packages. R is an open source programming language which works in different environment.
