谢谢您,这个只是我现在的想法,先试下吧。您觉得哪有问题?
You have to scan out someone who never/seldom try online shopping for luxury in the beginning of your questionnaire.Usually the questionnaire would have a question like: 你上次....是什麼時候? If he has experience and is suitable for the survey, then go on next question, otherwise simply say "thank you!" and stop the survey process. Think about it--what is the value of his/her feedback to your survey, if he/she is not your "target", or put in this way, do you think a man age over 90 and has no idea of online shopping would be your target?There are some more technical issues you have to take care when you get serious on this survey. If you are doing the research program (like PhD), the quality questionnaire will directly affect the quality of your research, better fix it at the early stage.
