Question: A social psychologist studied the effect of height on perceived overall attractiveness. Students were recruited to come to a research laboratory in pairs. They were left to sit in the waiting room for several minutes and then were brought to separate rooms, where their heights were measured. They also filled out a questionnaire that asked, among other things, that they rate the attractiveness of the person who had been sitting with them in the waiting room on a scale of 1 to 10.
a. In this study, are the independent and dependent variables nominal, ordinal, or scale?
b. Which graph or graphs would be most appropriate to depict the data? Explain why.
c. If height ranged from 58 inches to 71 inches in this study, would your axis start at 0? Explain.
