INTRODUCTION TO DATA ANALYTICS FOR FASTER DECISION MAKING

Data Analysis is an ever-evolving discipline with lots of focus on new predictive modeling techniques coupled with rich analytical tools that keep increasing our capacity to handle big data. However, in order to chart a coherent path forward, it is necessary to understand where the discipline has come from since its inception.

Today, more organizations are using data analysis tools and techniques in order to inform effective decision-making. This module also addresses some of the hurdles an organization faces when dealing with data overload and suggests some possible solutions to the problem. It is unfortunate that there is such a dearth of data analysts.

COURSE OBJECTIVES

In this course, the participants will learn:

• Types of data and how to group them
• Basics of data organization
• Basic statistics
• Central limit theorem
• Predict a process performance
• Comparing between populations
• Measure any changes in trend
• Explore ways to measure the performance of and improvement opportunities
• Discuss data distribution including Central Tendency, Variance, Normal Distribution, and non-
normal distributions.
• Explore different methods and easy algorithms for forecasting future results and to reduce
current and future risk.
