Repeat questions or blocks of questions are often found in product tests.
Where large sections of the questionnaire are repeated the project is sometimes called a trailer survey.
The analysis of questions that are repeated causes many problems to users. The same table can be produced in a variety of ways and it is often not clear which is required.
It is important to understand the implications of the various ways produce tables on repeat questions:
Companion analysis & export
If a block of questions is repeated in a project then once the first repeat is set up it is easy to “Copy” and “Paste special” to duplicate it.
For more guidance on setting up the project see: Repeat questions set up.
For 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 the data using QPSMR CL, see how to do this in 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 there are too many repeats then the survey can be treated as a traditional trailer survey using QPSMR CL.
