In a survey according to an embodiment of the invention, a subject may select from a list of items, such as activities. The subject may be asked to narrow the selection and then to supply information related to each of the remaining items. For example, the subject may be asked to indicate how much money the subject spent in the past 30 days on each of the selected activities. The subject may then be asked to assume that the spending must be reduced and to select or classify activities accordingly. Surveys may include various types of items, selection criteria, and/or information gathering that may be related, e.g., to selected items. Embodiments of the invention comprise surveys, computers and computer systems for administration of surveys, and computer-readable media encoded with instructions to cause computers or computer systems to administer surveys. |
