Overview of this book

In today's data-centric world, the ability to extract meaningful insights from vast amounts of data has become a valuable skill across industries. Exploratory Data Analysis (EDA) lies at the heart of this process, enabling us to comprehend, visualize, and derive valuable insights from various forms of data. This book is a comprehensive guide to Exploratory Data Analysis using the Python programming language. It provides practical steps needed to effectively explore, analyze, and visualize structured and unstructured data. It offers hands-on guidance and code for concepts such as generating summary statistics, analyzing single and multiple variables, visualizing data, analyzing text data, handling outliers, handling missing values and automating the EDA process. It is suited for data scientists, data analysts, researchers or curious learners looking to gain essential knowledge and practical steps for analyzing vast amounts of data to uncover insights. Python is an open-source general purpose programming language which is used widely for data science and data analysis given its simplicity and versatility. It offers several libraries which can be used to clean, analyze, and visualize data. In this book, we will explore popular Python libraries such as Pandas, Matplotlib, and Seaborn and provide workable code for analyzing data in Python using these libraries. By the end of this book, you will have gained comprehensive knowledge about EDA and mastered the powerful set of EDA techniques and tools required for analyzing both structured and unstructured data to derive valuable insights.

Dealing with Outliers and Missing Values

Outliers and missing values are common issues we will encounter when analyzing various forms of data. They can lead to inaccurate or biased conclusions when not handled properly in our dataset. Hence, it is important to appropriately address them before analyzing our data.

Outliers are unusually high or low values within a dataset that deviate significantly from the rest of the data points in the dataset. Outliers occur due to a wide variety of reasons; the common reasons are covered in this chapter. On the other hand, missing values refer to the absence of data points within a specific variable or observation in our dataset. There are several reasons why they occur; the common reasons are also covered in this chapter.

When handling outliers and missing values, proper care needs to be taken because using the wrong technique can also lead to inaccurate or biased conclusions. An important step when handling missing values and outliers is...
