Ranking questions allow respondents to rank items by dragging and dropping them into an ordered list of a specified length. This question type is most relevant when you have a list of potentially desirable options and need to determine which one to use.
Let's say your company is redesigning their logo and wants to run a concept testing survey to help them decide which design they should use. The ranking question allows you to compare and rate attributes and takes the elements into account in the data analysis. The ranking question will be useful in uncovering the favorite logo amongst the options as it requires respondents to compare the concept designs, rank from based on preference, and select their top choice.
When it comes time to analyzing a survey, users can easily identify the top ranked logo design. To understand how strongly they prefer their list of preferences, you may add follow up rating questions.
