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.

Performing Multivariate Analysis in Python

A common problem we will typically face with large datasets is analyzing multiple variables at once. While techniques covered under univariate and bivariate analysis are useful, they typically fall short when we are required to analyze five or more variables at once. The problem with working with high-dimensional data (data with several variables) is a well-known one, and it is commonly referred to as the curse of dimensionality. Having many variables can be a good thing because we can glean more insights from more data. However, it can also be a challenge because there aren’t many techniques that can analyze or visualize several variables at once.

In this chapter, we will cover multivariate analysis techniques that can be used to analyze several variables at once. We will cover the following:

  • Implementing cluster analysis on multiple variables using Kmeans
  • Choosing the optimal number of K clusters in Kmeans
  • Profiling...
