When to Use a Matrix Question
A matrix question offers a way to combine several items that have the same multiple choices. It is often used when a Likert scale is employed. For example, you have just completed a course, and the instructor wants to know how satisfied you were with various aspects of the class. She/He would likely ask questions on your opinion about various aspects of the course, and provide the following response options for you:
- Very Satisfied
- Somewhat Satisfied
- No Opinion
- Somewhat Unsatisfied
- Very Unsatisfied
This allows several questions to be combined, so that screen space can be saved, and your respondents can answer the question quickly.
