A closed-ended question is a survey question that provides respondents with a set of predefined response options to choose from, producing quantitative data that can be counted, compared, and trended across respondents and over time.
Types of Closed-Ended Questions
- Multiple choice (single select) - respondents choose one option from a list. Used for categorical data where only one answer applies.
- Multiple choice (multi-select / checkboxes) - respondents can select all applicable options. Used when multiple responses may apply.
- Rating scales - respondents rate an item on a numerical or labelled scale, including Likert scales, satisfaction scales, and frequency scales.
- Rank order - respondents order a list of items by preference or importance. Cognitively demanding for more than five items.
- Matrix questions - multiple items rated on the same scale, presented in a grid. Efficient for related item batteries but prone to straight-lining when long.
- Dropdown lists - respondents select from a dropdown menu, useful when the list is too long to display as radio buttons.
- Dichotomous questions - Yes/No or True/False. Simple but limited in nuance.
When to Use Closed-Ended Questions
Closed-ended questions are appropriate when the range of meaningful responses is known in advance, when quantitative comparison across respondents is required, when tracking changes over time using consistent measurement, when the survey will be completed on mobile where typing is difficult, and when the research team does not have capacity to analyse qualitative text responses.
Closed-Ended vs Open-Ended Questions
The choice between closed and open-ended questions is fundamentally a choice between measurement precision and discovery. Closed-ended questions measure; open-ended questions explore. Most professional surveys use both.
The "all options" problem is the primary limitation of closed-ended questions: if the response set does not include the option most relevant to a respondent, they must select a less accurate alternative or use an "Other (please specify)" option. Always include an "Other" option for multiple-choice questions where the list may not be exhaustive.
Frequently Asked Questions
Multiple choice (single select) and Likert rating scale questions are the most common in professional surveys. Rating scales are particularly prevalent in CX surveys for metrics like NPS, CSAT, and CES.
For multiple-choice questions where the list of options may not cover all possible responses, an 'Other (please specify)' option should be included. For rating scales and Likert items where the scale itself is the complete response set, 'Other' is not applicable.
Pirai AI identifies closed-ended question types from source document structure and maps them to the appropriate question type in the target platform. Multiple choice questions map to radio button or checkbox questions. Rating scales map to scale questions.
Closed-ended questions capture what you anticipate respondents will say. They cannot capture unexpected insights outside the predefined option set. For tracking known constructs over time, closed-ended questions are ideal. For understanding the 'why' behind scores, supplementing with open-ended follow-up questions is necessary.
