Essays / Antigone: law and literature, can a survey be used in an essay? [2]

Howdy folks,

I have to read the Greek tragedy Antigone for law school, i want to score really high marks with my essay on law and culture/ideology. My goal is to survey 50 people after watching a live performance of the tragedy, questioning the effects of culture and ideology on personal perceptions of the law etc. I don't want to rehash the work of other academics.

QUESTION, is it acceptable to use survey/questionnaires in an essay as supporting evidence? i have never heard of it done at my law school. I will of course look at various academic literature but i want to go above and beyond what is required. Any suggestions? Many Thanks
