When users answer questions there is a natural bias towards selecting the top and bottom answers listed on the page. In order to remove the bias you should enable Answer randomization on questions where it makes sense.
Answer Randomization is not suitable for all question types, for example a list of country's which you would want to appear alphabetically or a long list of products that would be better grouped logically to aid the respondent.
To enable Answer Randomization
- Go to the Page Editor
- Hover over a question and select Edit
- Enable the Answer Randomization check box.
