  1. Do better-looking NFL quarterbacks play better on field? Authors L. Jon Wertheim and Sam Sommers set out to investigate this question and several others. To judge the attractiveness of each team's starting quarterback heading into the2014 session, they asked people to rate headshots of the quarterbacks on a 1 - 10 scale and averaged the results for each quarterback. Here is a scatterplot showing the relationship between attractiveness and quarterback rating for the 31 rated quarterbacks who played during that season. The correlation for these data is r = 0.17.
