QS:Min answers

最小回答数 (min_answers)

説明

この機能は、複数選択質問で一定数の回答を選択させる場合に使用します。

有効な値

• Any integer value above 0
• Any number
• Any SGQA code
• Any question code (variable name)
• Any equation, using Expression Manager syntax, without surrounding curly braces.

Example

If set to X (a random number), the users can submit the survey form if they select at least X checkboxes. If this option is utilised for ranking questions, this ensures that at least three items are ranked before allowing the respondent to submit the answers/survey.

Please note that if you use this attribute with Ranking questions, you have to set the question to non-mandatory. Otherwise, all the items need to be ranked which is counter-intuitive if you decide to use the min_answers function too.
