5.6 Design a questionnaire. It should contain about 20 questions and you should use as many of the different types of question as possible. Pay particular attention to the concerns discussed at pp. 153–7 of the chapter. The objective is to investigate respondents’ attitudes to music CDs and their purchasing habits. Pilot your questionnaire on 12–15 people (but preferably not people on the same course as you), analyse the results and then make any adjustments. Within your seminar group, be prepared to discuss the rationale behind your questionnaire, the outcome of the pilot and any data analysis problems.
