In this type of question the respondent is asked to rank a number of options in order of importance or preference or some other factor.
Example:

Please say how important you think the following are when choosing a leisure centre to visit by putting a ‘1’ next to the most important, a ‘2’ next to the second most important and so on.

Sports facilities  
Distance from home  
Changing rooms  
Showers

With this sort of question, respondents find it difficult to rank more than about 5 aspects.
