Rank-order questions are used in those cases when you want the users of your program to reorder a set list of options. For example:
- to express preference
- to rearrange a list by the size of the items in it
- any time you want the users choose the order in which the elements of a list are arranged.
In order to create a rank-order question, you need to indent
*type:ranking under the
*question and provide the list to rank:
*question: Rank these creatures from best to worst
Users can reorder the list doing drag and drop. Alternatively, if they are not using a touch screen, they can select the position of any given answer from the dropdown list that is displayed:
Here is a more detailed example of how rank-order questions work:
*question: Enter the books that you read last month:
*tip: Type one book per line
*question: Order the books that you read by the time it took you to read them:
*tip: The book that took the longest should be up top
The first question asks users to type in a list of the books they read that month. Their answer is saved in the variable
booksRead. Let's say that this is the user's response:
["A Room of One's Own", "Catch-22", "Demon Copperhead", "One Flew Over the Cuckoo's Nest"]
The second question is the rank-order one, where
booksRead is displayed and the user has instructions to reorder them.
If they clicked Next after reordering them as shown, the value of
orderedBooks would be
["Demon Copperhead", "One Flew Over the Cuckoo's Nest", "A Room of One's Own", "Catch-22"]
Note that, although both collections have the same elements, they are different because the elements are in different order.
