In one study, participants view three photos of job applicants. The applicants could have a scar, birthmark, or no blemish on their face. The researchers want to know if having some sort of facial mark influences participants' likelihood of selecting an applicant to hire. The participants rate their likelihood of hiring the applicant on a scale of 0 (definitely would not hire) to 10 (definitely would hire). Those data appear in the table below along with some "summary" data.
