Practical Data Analysis Using Jupyter Notebook

By: Marc Wintjen

Overview of this book

Data literacy is the ability to read, analyze, work with, and argue using data. Data analysis is the process of cleaning and modeling your data to discover useful information. This book combines these two concepts by sharing proven techniques and hands-on examples so that you can learn how to communicate effectively using data. After introducing you to the basics of data analysis using Jupyter Notebook and Python, the book will take you through the fundamentals of data. Packed with practical examples, this guide will teach you how to clean, wrangle, analyze, and visualize data to gain useful insights, and you'll discover how to answer questions using data with easy-to-follow steps. Later chapters teach you about storytelling with data using charts, such as histograms and scatter plots. As you advance, you'll understand how to work with unstructured data using natural language processing (NLP) techniques to perform sentiment analysis. All the knowledge you gain will help you discover key patterns and trends in data using real-world examples. In addition to this, you will learn how to handle data of varying complexity to perform efficient data analysis using modern Python libraries. By the end of this book, you'll have gained the practical skills you need to analyze data with confidence.

Reporting results

How to present your analysis results will vary by the audience, the time available, and the level of detail required to tell a story about the data. Your data may have an inherent bias, be incomplete, or require more attributes in order to create a complete picture, so don't be afraid to include this information in your analysis. For example, if you have done some research on climate change, which is a very broad topic, presenting the consumers of your analysis with a narrow scope of assumptions specific to your dataset is important. How and where you include this information is not as important as ensuring it is available for peer review.

Storytelling

Storytelling with data requires some practice and you need time to sell your message to the audience. Like any good story, presenting the data results in a cadence with a beginning, middle, and end will help with the flow of the analysis being consumed. I also find using analogies to compare...
