Chapter 1, Exploratory Data Analysis Fundamentals, will help us learn and revise the fundamental aspects of EDA. We will dig into the importance of EDA and the main data analysis tasks, and try to make sense out of data. In addition to that, we will use Python to explore different types...
The str() function returns many useful pieces of information, including the above useful outputs and the types of data for each column. In this example, “num” denotes that the variable “count” is numeric (continuous), and “Factor” denotes that the variable “spray” is categorical with...
