A respondent's answer to an open-ended question can be coded into a response scale afterwards, [28] or analysed using more qualitative methods. Two studies demonstrate both the importance of question wording and the differential impact it can have on different subsets of citizens. [27]

Conduct proper qualitative or other research to properly identify and describe all items of interest. [24] Construct a statistical design that indicates what items are to be presented in each set of items ("choice set") – designs may come from publicly available catalogues, be constructed by hand, or produced from commercially available software.
A research design typically outlines the theories and models underlying a project; the research question(s) of a project; a strategy for gathering data and information; and a strategy for producing answers from the data. [1] A strong research design yields valid answers to research questions while weak designs yield unreliable, imprecise or ...
