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.

Analyzing Time Series Data in Python

In this chapter, we will learn how to analyze time-dependent data, also known as time series data. Time series data is data that changes over time; it is a sequence of data points that are recorded over regular time intervals such as hourly, daily, weekly, and so on. When we analyze time series data, we can typically uncover patterns or trends that repeat over time. Time series data has the following components:

  • Trend: This shows the overall direction of the time series data over time. This can be upward, downward, or flat.
  • Seasonal variations: These are periodic fluctuations that reoccur over fixed timeframes. In simple terms, seasonality exists when a pattern is influenced by seasonal factors, for example, the quarter of the year or the month of the year. Seasonal patterns typically have a fixed period since they are influenced by seasonal factors.
  • Cyclical variations: These are fluctuations that happen over time but without a...
