About Logic
If your form includes multiple pages, it’s possible that not all of them apply to every respondent. Logic allows you to create customised paths for your respondents, based on the answer selections they make. It can also be used to disqualify people who do not fit the criteria for your research, or those who do not give consent for their data to be processed. Logic works the same way whether your form is a Survey or a Quiz.
Note: Logic does not work by hiding/showing sets of questions on-page, but rather by determining which page to send respondents to based on what answers they do/don’t select.
Both kinds of Logic below are set up in the same place: open the Form tab in the builder and click the Question logic tab in the sidebar to see everything at a glance, or expand any question’s ⋮ menu and choose Logic to edit it directly.
Page Logic
Section titled “Page Logic”Page Logic concerns where a respondent is sent once they click ‘Next Page’ (or move on to the next question, on a single-question-per-page form) — shown in the sidebar as Default end of page skip to: for each page. It’s the destination used for anyone who doesn’t trigger a more specific Question Logic rule on that page.
By default, it sends respondents to the next chronological page (the one placed directly after it in the page list), but can be set to send respondents to any page that exists AFTER the page they’re currently on, or to an Exit page.
Question Logic
Section titled “Question Logic”Question Logic works by filtering respondents to separate pages based on the answer selections they’ve made — set per answer option, from a question’s ⋮ → Logic menu.
Note: This feature requires some planning, and should be written out on paper before constructing an online form.
Qualification Questions
Section titled “Qualification Questions”By applying Logic in this way, you can disqualify participants from completing your form based on any information they give you. This is particularly useful if you only want to collect results from a target audience or focus group, as you’ll avoid sifting through piles of irrelevant data. Respondents will also appreciate this, as they won’t be wasting time filling out a form where their results aren’t useful.
Consent Pages
Section titled “Consent Pages”Consent Pages work similarly to Qualification Questions, as you’d essentially be disqualifying all those who do not give consent. We would suggest that you include this page at the beginning of your form, to avoid wasting the time of your respondents or gathering data you won’t need.
Information Request Forms
Section titled “Information Request Forms”Equally, you could use Logic to supply respondents with methods of providing further information regarding an answer option they’ve selected. E.g. if the purpose of your form is to collect customer feedback, you would include a question such as ‘were you happy with our level of service?’. If the customer was to say ‘no’, you may want more information regarding their experience and how your service could improve. You can use Logic to direct those ‘customers’ to a page created for that specific purpose.
Logic incorporates an element of intelligence into your form; which ultimately saves your respondents time in completing it, and saves you time in filtering out respondents that would provide irrelevant data. Using logic is likely to increase the completion rate of your form, as respondents will only see pages that are relevant to them, and are less likely to leave before finishing.
