Overview of this book

Learning Tableau has never been easier, thanks to this practical introduction to storytelling with data. The Tableau Workshop breaks down the analytical process into five steps: data preparation, data exploration, data analysis, interactivity, and distribution of dashboards. Each stage is addressed with a clear walkthrough of the key tools and techniques you'll need, as well as engaging real-world examples, meaningful data, and practical exercises to give you valuable hands-on experience. As you work through the book, you'll learn Tableau step by step, studying how to clean, shape, and combine data, as well as how to choose the most suitable charts for any given scenario. You'll load data from various sources and formats, perform data engineering to create new data that delivers deeper insights, and create interactive dashboards that engage end-users. All concepts are introduced with clear, simple explanations and demonstrated through realistic example scenarios. You'll simulate real-world data science projects with use cases such as traffic violations, urban populations, coffee store sales, and air travel delays. By the end of this Tableau book, you'll have the skills and knowledge to confidently present analytical results and make data-driven decisions.

Preface

Scatter Plots with Trend Lines

In this section, rather than focusing on the math that trend lines are dependent on, you will look at them from an analyst/data developer perspective, and will see some common use cases in business.

Trend lines are used to observe relationships between variables. For example, they could be used to see the relationship between force and acceleration, or to track the relationship between sales and profits over a given time period. They are statistical models that are useful in estimating future patterns or trends based on historical data points.

Adding trend lines in Tableau is fairly simple. In this section, you will explore the variations of trend lines available. Figure 5.27 shows the five types of a trend line in Tableau. You will get a thorough definition of each as well as their most common applications a little later in this section.
