Overview of this book

Hands-On Data Preprocessing is a primer on the best data cleaning and preprocessing techniques, written by an expert who’s developed college-level courses on data preprocessing and related subjects. With this book, you’ll be equipped with the optimum data preprocessing techniques from multiple perspectives, ensuring that you get the best possible insights from your data. You'll learn about different technical and analytical aspects of data preprocessing – data collection, data cleaning, data integration, data reduction, and data transformation – and get to grips with implementing them using the open source Python programming environment. The hands-on examples and easy-to-follow chapters will help you gain a comprehensive articulation of data preprocessing, its whys and hows, and identify opportunities where data analytics could lead to more effective decision making. As you progress through the chapters, you’ll also understand the role of data management systems and technologies for effective analytics and how to use APIs to pull data. By the end of this Python data preprocessing book, you'll be able to use Python to read, manipulate, and analyze data; perform data cleaning, integration, reduction, and transformation techniques, and handle outliers or missing values to effectively prepare data for analytic tools.

Introducing the case study

As the world started grappling with the ramifications of COVID-19, healthcare systems across the globe started dealing with the new overwhelming burden of caring for the people infected with the disease. For instance, in the US governments, all levels – Federal, State, and local, had to make decisions so they can help the hospitals as they struggled to shoulder the crisis. The good news is that database and data analytics technologies were able to create real value for these decision-makers. For instance, the following figure shows a dashboard that monitors the COVID-19 situation for Los Angeles County in the State of California in the United States. The figure was collected from http://publichealth.lacounty.gov/media/coronavirus/data/index.htm on October 4, 2021.
