Specifically, survey structure can refer to the number of questions every page, the survey logic, or the inspection length.

Every part of survey framework can contribute to response bias and also drop-outs. As with the other creates of response bias, you deserve to structure your survey by thinking about how respondents will certainly react come each facet of her survey.
