The method of sampling used is voluntary response, as the students who are willing to give their opinion are being sampled. This is not a random sample, as it is not representative of all students at the university. It is also not a census, as not all students are being included. A Gallup Poll is a type of survey research conducted by a polling organization and would not apply in this case.
