Using Questionnaires as a Research Technique

During our  lesson we were given a flawed questionnaire and asked to rectify it to an accurate standard which could be used as a form of research. The bad questionnaire asked very indirect questions and had little focus on the initial question which was basically 'to find out about downloading and streaming habits among a particular age group'. It used indirect and irrelevant questions such as ' Do you feel guilty about using illegal websites to download media?' questions like these fail to pinpoint the initial reason for the question, and do not actually help retrieve neccessary data/research in relation to the initial question. Asking very personal questions such as 'Name, Address etc) make the questionnaire non confidential which could make many people feel opposed to fill out the questionaire. Asking for questions such as 'Gender, Age, Status' are useful to the researcher as it gives more information as to the motives behind illegal downloading based on age, financial group based on status (employed, unemployed etc) and sex to indetify if there is a correlation between a gender and illegal download rates.
