whys it important to produce a questionnaire?

Its very important to my research task, to produce a questionnaire and ask a range of different people to fill it out. This is because by evidence sustained from the results of the questionnaire I can establish my target audience for my magazine and therefore have a clear idea of what needs to be included to appeal to my specific target audience. Furthermore I can identify what genre of magazine would sell best, because of data collected from the questionnaire. By analysing the data collected I can include all important conventions, and therefore make my magazine I success.
