Introduction to repeat questions
You can find repeat questions or blocks of questions in product tests. If you repeat large sections of the questionnaire, the project is sometimes called a trailer survey.
The analysis of questions that are repeated causes many problems to users. You can produce the same table in a variety of ways when it is not clear which you require. It is important to understand the implications of the various ways produce tables on repeat questions:
Companion analysis & export
If you have a block of repeat questions in a project then, once the first repeat is set up, you can “Copy” and “Paste special” to duplicate. For more guidance on setting up the project see Repeat questions set up.
If you have a projects where a set of questions are repeated for different products, please visit Overlay tables for repeated questions.
For product tests it is sometimes necessary to have each product in a fixed place in the data, even though the questionnaire has the products in different places. For more information, please visit the De-rotate repeated questions page.
Using QPSMR CL
For Companion Reflect you may wish to add levels to data using QPSMR CL, please see Levels in Reflect.
Where there are a lot of repeated questions which make overlaying tables impractical you can split records with QPSMR CL so that each repeat becomes a new record. For information, please see How to split data records
If you have too many repeats, then you can treat the survey as a traditional trailer survey using QPSMR CL.
