Visualizations and Simple Metrics

Summary

This chapter discusses the yin‐and‐yang of visualizations (pie charts and scatterplots) and summary statistics (averages and correlations). Pictures are the most powerful form of communication, but they are imprecise and often hard to create; numbers are objective, but often mis‐leading. If you understand how these approaches complement each other, you can use them together to unlock the stories within your data.
