The 31 individualswere made to appear as similar as possible to account for other variables that may play a role in theoffer price of a car. The following data are based on the results in the article and represent the profiton the initial price offered by the dealer. Ayres wanted to determine if the profit based on the initialoffer differed among the four groups. Source: Ian Ayres. “Fair Driving: Gender and Race Discrimination in RetailCar Negotiations."
