# Business Analytics using R

Business Analytics, or simply analytics, is the use of data, information technology, statistical analysis, quantitative methods, and mathematical or computer-based models to help managers gain improved insight about their business operations and make better, fact-based decisions.Thus Business Analytics is “a process of transformingdata into actions through analysis and insights in the context of organizational decision making and problem solving.”

This is an introductory training on analyzing different aspects of businesses using R. This training covers areas that include introduction to R, the R basics, logical operator, data structure, data management in R, data visualization and graphics in R, and basic statistical functions and inferences.

LEARNING OUTCOMES

After completion of this training, the participants will be able to:

• use real data sets and perform analysis using R

• understand different types of the data

• make graphs and charts by using R

• use R for various statistical computations and

inferences

• apply different statistical test in real data

• use regression analysis in real data
