Racer is a game where the player can race a variety of racecars on multiple tracks. Each car body, engine and set of tires impacts the speed and acceleration of the cars. Players can choose any options they like, but they will develop better strategies (i.e. improve their chances of winning) if they thoroughly understand the data and techniques for analyzing it.

This activity uses the Racer game to demonstrate the challenges in drawing conclusions in hypothesis tests. Students recognize that multiple sources of bias and confounding variables can cause the p-value to be unreliable. The emphasis is on using data to draw conclusions, even when the standard assumptions for hypothesis tests may not hold.
