To see if smiling had a different effect on liking based on gender, Carol brought in a group of volunteers. As each volunteer entered the first room, a greeter smiled at them before ushering them into a second room. In the second room, a greeter of a different gender from the first smiled at them before ushering them into a third room. In the third room, a sign instructed each participant to fill out a form evaluating how much the participant liked each of the greeters. In the end, each participant rated two greeters of different genders. What type of analysis would be appropriate?
