Data Science Comprehensive Training

Your working lives are flooded by large amounts of information, but not all of them are useful data. Therefore, it is essential for us to learn how to apply data science into every aspect of our daily lives from personal finances, reading and lifestyle habits, to making informed business decisions. In this course you will learn how to leverage on data to ease life or unlock new economic value for a business.

This course is a hands-on guided course for you to learn the concepts, tools, and techniques that you need to begin learning data science. We will cover the key topics from data science to Big Data, and the processes of gathering, cleaning and handling data. This course has a good balance between theory and practical applications, and key concepts are taught using case study references. Upon completion, participants will be able to perform basic data handling tasks, collect and analyse data, and present them using industry standard tools.
