Skip logic is one or more set of conditions that trigger skipping ahead in a survey. Skip logic is defined at the level of a survey page. Each skip logic condition group defined in a survey can trigger the skipping ahead to a subsequent page in the survey, if the condition group if true for a response. Whether or not the skipping occurs is based on the respondent's answers for question in page preceding the page with the condition. An alternative to skip logic is page conditions.
For example, in a survey about cell phone usage, the first page might contain a question asking the respondent if they own a cell phone. If the respondent answered "No" to the question about ownership of a cell phone, a skip logic condition group can be used in this page to bring the respondent to the completion page for the survey, thereby skipping all other pages in the survey.
Skip logic is added to a page from the Page detail screen. A skip logic condition group for a page is executed when the respondents presses the "next page" button.
Skip logic is defined as condition groups. Each group comprises a set of conditions and specifies the page to skip to if the group is true. Each condition in a skip logic group is evaluated individually and the results for the group are combined together to decide whether to skip to the destination page.
Conditions can be defined for the answers to question in the survey and for values of URL parameters for the response. If a skip logic condition group includes conditions for both answers to questions and URL parameters, the condition group will be true if both sets of conditions are true.
