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

In conducting market research, an important key in obtaining unbiased responses is to avoid asking survey participants questions that may influence the responses they provide. Avoiding survey bias helps eliminate responses that may invalidate or skew the data collected. It is quite easy and common for a company or individual without the proper market research training/knowledge to err in this way.  This applies to many things, such as the way a question is phrased, to the types of responses that are available to choose from, to the way that an interviewer presents the questions if data is being collected by phone or in-person.
