Primary reserch

I have made a survey which I will hand out to the whole of my sixth form , and analyse results . Before I asked my head of sixth form for permission to send it out , I sampled my test questions with two participants and asked for feedback on how they perceived and understood the questions . Below is a print screen on some of the answers they gave to my initial survey .I have now edited some of my questions so they are more understandable and not leading . 

 The question which appears as unanswered is one I have added since the initial one .
