The main objective of this introductory chapter is to revise the fundamentals of exploratory data analysis (eda), what it is, the key concepts of profiling and quality assessment, the main dimensions of eda, and the main challenges and opportunities in eda. In this lecture we will see how to use vizualization, transformation and modeling to explore your data in a systematic way. this task is usually referred by statisticians as exploratory data analysis, or eda for short. Now that we have had a look at what variables we have, we need to start looking for other aspects of the exploratory data analysis (eda) process. these are some of the things to look out for: here we start the data exploration of the categorical variables (also called factors).
