how to / create centres / business plan / questionnaire / data Send out or collect information from enough people to give a good representative sample. 100 is good as it is both large enough and easy to turn into a percentage. If not, try to collect 50. If you are going to get 100 returned by post you may need to send out 500 or even more. So consider collecting answers in a meeting, in the street, door to door, or by phone survey. A local school or the local newspaper may help you. Processing and Analysing Data Once all your questionnaires have been completed, you must process and analyse the information you have obtained. You need to check all the questionnaires to ensure they have been filled in correctly. Once you have ensured that the information is satisfactory you can count responses. The easiest way is to record answers on an unused questionnaire in the form of tally. But you can draw up tables and charts to analyse the information you have gathered. The answers to open questions often need studying separately to get a real feeling for opinions and views. This kind of answer is useful to quote to give a real idea of what people think or the difficulties they face. Once you have carried out your research you should be aware of the needs of your target client groups and be in a position to define exactly what you are offering in terms of products and services, how you will price them, where they will be offered (place) and how you will promote them. This is known as the Marketing Mix or 4 Ps: Product (or service), Price, Place and Promotion. how to / create centres / business plan / questionnaire / data
