Module Name: Deep Survey
Deep Survey is a module which aims to turn Drupal into a market and social research surveying tool. It allows privileged users to add surveys to a site. These surveys consist of questions which then in turn consist of answer lists – both of these are separate content types. Other Drupal users may complete the surveys, being asked one question after another and responding via the answer lists. It is possible to have the user skip one or more questions based upon their responses to earlier questions.
