In this lesson, you learned a framework for describing the distribution of a dataset, which includes the following five features:

• Center
• Spread
• Skew
• Modality
• Outliers

If you’re curious, while the dataset in this study showed the average amount charged by hospitals for a given condition, the amount paid is far less. This is often due to nature of the United States healthcare system, where private insurers negotiate down the charges levied by hospitals.

The small histogram on the left side of the plot displays the actual amount of money paid to the hospital.
