Research - Questionnaire (Target Audience)

After looking at the guidelines the BBFC have in place for certificates '15' and '18,' I have decided that, indeed, my film trailer will fall under one of these guidelines due to its horror content. I then decided to create a questionnaire to confirm my target audience and what they want/expect to see from a typical horror film.
My questions were as followed:

1. How old are you?
   - 14>18  - 19>25  - 26+
