Translations:How to design a good survey (guide)/153/en

In obtaining market research, one of the most critical things to avoid is the issue of survey bias - that is, asking the respondent questions which may influence the results he or she provides and thus invalidates or skews your data.  It is very easy and common for a company or individual without the proper market research education and experience to err in this way.  This extends to many things, such as the way a question is phrased, to the types of responses which are available, to the way that an interviewer presents the questions if data is being collected by phone or in-person.
