Perceived malevolence of uniforms and penalies for National Football League (NFL) teams


A dataset with 28 observations on the following 3 variables.

NFLTeam Team name
NFL_Malevolence Score reflecting the "malevolence" of a team's uniform
ZPenYds Z-score for penalty yards


Participants with no knowledge of the teams rated the jerseys on characteristics such as timid/aggressive, nice/mean and good/bad. The averages of these responses produced a "malevolence" index with higher scores signifying impressions of more malevolent uniforms. To measure aggressiveness, the authors used the amount of penalty yards converted to z-scores and averaged for each team over the seasons from 1970-1986.
