# Matrix Question

A matrix question (or grid question) displays multiple sub-questions sharing the same response scale in a table, letting respondents rate many items efficiently.

Matrix questions compress what would otherwise be 5-15 separate Likert questions into a single screen, which is efficient but introduces real risks: straight-lining (respondents picking the same column for every row to save effort), mobile usability collapse (most platforms render matrices as stacked Likert on small screens), and fatigue. Best practice: limit matrices to 5-7 rows, randomize row order, monitor straight-line rate (>15% is a warning, >25% requires data cleaning), and prefer separate questions for the most important items.

## Example

Rate satisfaction with each of these 6 features on a 1-5 scale (Onboarding, AI assistant, Templates, Analytics, Integrations, Support). Straight-line detection finds 19% of respondents picked '4' for every row — these are flagged for QA review.
