## How should police departments address excessive use of force?

How should police departments address excessive use of force? A number of high-profile cases have painted a disturbing picture of how police officers treat the people they’re supposed to keep safe.

In this lesson, students compare the distributions of excessive force of two police departments and explore how the shape of the distribution affects the effectiveness of different solution attempts.

### REAL WORLD TAKEAWAYS

• Effective policy solutions won’t necessarily be palatable or feel fair to society.

### MATH OBJECTIVES

• Given a graphical display of univariate data, use the mean, median, and mode to describe the “typical” case
• Analyze and interpret graphical displays of univariate data to answer multi-step problems
• Compare a normal vs. power law distribution, and understand how the shape of a distribution affects real-world policy

Great anytime, including at the beginning of a unit before students have any formal introduction to the topic.

Content Standards S.ID.2 Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets. S.ID.3 Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers). S.IC.6 Evaluate reports based on data.
Mathematical Practices MP.3 Construct viable arguments and critique the reasoning of others. MP.4 Model with mathematics. MP.5 Use appropriate tools strategically.
