A drag and drop question is a rank order scaling question. Rank order scaling questions allow a certain set of options (brands or products, etc.) to be ranked based upon a specific attribute or characteristic.
To eliminate bias, you can randomize the order the options are displayed to the respondent.
Example: Let's assume that Toyota, Honda, Mazda, and Ford are most likely to be purchased. You wish to ask respondents to rank the following brands according to their reliability: Honda, Toyota, Mazda, and Ford. The respondents can drag and drop these options to re-order and rank them.
How can I add a drag and drop order / rating question?
How the question will appear to the respondent is shown below.
