Learn@UW - Problems Taking Branching Survey with Unanswered True/False or Multiple-Choice Questions
In a branching survey, if a user taking the survey neglects to answer a Muliple-Choice or True/False question, no warning is issued that no choice has been selected and no branching or skipping subsequent questions is ever done.
This holds even if both (True/False) or all possible (Multiple-Choice) responses are to skip ahead to the same question. This can be misleading to the user who may be unaware of forgetting to answer a question and is suddenly presented with an irrelevant question that should have been skipped.
This is a known issue.
Users taking a branching survey should be reminded to make sure they answer all True/False and Multiple-Choice questions as they appear before proceeding to the next question.
