Web Survey Bibliography
How do nonresponse options like a DK option or a filter question affect the item nonresponse and distribution of opinions? This question will be answered in a comparative setting by conducting and comparing three internet survey experiments which examine the effects of question design and in particular nonresponse options like the DK option and the filter question. The experiments are carried out with three different internet panels. To differentiate between the effect of nonresponse options, five issues areas are included which each consist of replicated questions.
