What is Matrix question?
A matrix question (also called a grid question) presents a set of related items or statements in rows with a common response scale in columns, letting respondents answer the same question type for multiple items at once. It’s commonly used for Likert-style ratings (e.g., strongly agree → strongly disagree).
A matrix question groups several similar questions together in a compact table so each row is a separate item and each column is a shared response option. For example, a survey might list several service aspects (cleanliness, staff helpfulness, opening hours) as rows and offer the same 1–5 satisfaction scale as columns. Matrix questions reduce repetition for respondents and make it easy to compare responses across items, but they require careful design to avoid confusing or overloading participants and can pose accessibility challenges on small screens or with assistive technologies.
Usage example
A school survey uses a matrix question to ask parents to rate: (rows) Clear communication from school
, Friendliness of staff
, Safety of premises
with a shared 1–5 satisfaction scale (columns). In Hearo, the creator writes the matrix once, enables the languages needed, and parents complete the matrix in their preferred language while admins see translated responses back in the admin language.
Practical application
Matrix questions save space and speed up completion when you need consistent ratings across several items, making comparisons and reporting easier. In multilingual contexts, they keep wording consistent across languages (one source to translate), reduce the number of separate questions to translate, and simplify review because the same response scale applies everywhere. However, use them only when each row is comparable and short, ensure mobile-friendly layout, and provide clear instructions — and in Hearo, leverage participant feedback and translation review to catch ambiguous phrasing that could affect how different language groups interpret the scale.
FAQ
When should I avoid using a matrix question?
Avoid matrices when items are long, complex, or not directly comparable — they increase cognitive load and can confuse respondents. If you need different response types (e.g., a mix of ratings, dates, or free text) or expect detailed answers per item, use separate questions instead.
Are matrix questions accessible on mobile and for screen readers?
They can be, but require careful design. On small screens, present rows stacked with clear labels rather than a wide grid. Ensure each row and option is properly labeled for screen readers. Test the matrix on mobile and with assistive tech or use Hearo’s simpler single-question layouts when accessibility is a priority.
Do matrix questions affect response quality (e.g., straight-lining)?
Yes — when respondents want to finish quickly they may give the same answer across all rows (straight-lining) or skip thinking through each item. Keep the number of rows reasonable, mix item phrasing, and consider breaking large matrices into smaller sections to reduce satisficing.
How does multilingual support work for matrix questions in Hearo?
You create the matrix once and select target languages; Hearo translates the row labels, column options, and instructions for participants. Responses are collected in the participant’s language and shown to admins translated back into their chosen language. Participants can flag wording problems so translations can be reviewed and improved.
