A mаrketing firm is interested in leаrning аbоut millennials’ preferences оn learning experiences. In оrder to do this, they survey students at a university. They ask them six questions as follows. They consider the following leaning experiences: a traditional class, a flipped course (half of the content is delivered online), and an online class. For each pair of these alternatives, say a and b, they ask the students “is a at least as good as b.” In order to make this operational, they provide the students with a picture in which the three alternatives are depicted as circles with their description next to it. The students are asked to draw arrows between the alternatives whenever the answer to a question is affirmative. That is, if a student finds alternative a is at least as good as alternative b, the student is asked to draw an arrow from the circle with label a to the circle with label b. (No question is a at least as good as a was asked; assume that the answer to each of these trivial questions is affirmative.) Suppose that a student’s answer are as follows: one arrow from the traditional class to the online class; an arrow from the online class to the flipped course; and an arrow from the flipped course to the traditional class.
