Question Answered step-by-step This data set, “Beer Goggles”, provides median attractiveness… This data set, “Beer Goggles”, provides median attractiveness ratings of 50 attractive or unattractive faces after consuming different amounts of alcohol. Variables: FaceType Attractiveness of the rated faces based on facial symmetry (‘0’ = unattractive, ‘1’ = attractive).
