EDA is an important first step in any data analysis. Exploratory Data Analysis is a process of examining or understanding the data and extracting insights or main characteristics of the data. To give insight into a data set. Discovered in the 1970s by American mathematician John Tukey, exploratory data analysis (EDA) is a method of analysing and investigating the data sets to summarise their main characteristics. I often draw a distinction between exploratory and explanatory data analysis. Our goal is to summarize the main characteristics of the data by exposing trends, patterns, and relationships that may not be apparent at first glance. In other words Exploratory data analysis. In this 1-hour long project-based course, you will learn exploratory data analysis techniques and create visual methods to analyze trends, patterns, and relationships in the data.
