It's the age question you also have to tick a gender box at the bottom of the age ranges. I think the survey would have been better if that question had been separated out. Anyway I've filled it in for you
I would like to know what the purpose of the survey is (I have filled it in). I trust you have distributed it to a lot of other people apart from those on this forum. If you haven't, and when writing it up, you will have to explain your sampling method, and unless your thesis is about 'Holiday preferences of travel-based forum members', you will have to extensively explain the inherent bias! Already there seems to be a problem that retired people may not be represented. Or perhaps this is a trial questionnaire which will highlight problems- that are usually unexpected - that you can refine when you do your final version.
Good luck anyway! --- old post above --- --- new post below ---
