If you want your audience to get a list of items and rank them in a certain order, you can use the Ranking question type.
Create a Ranking question
This is how you create a Ranking question with Mentimeter:
Create a new slide
Choose the Ranking question
Fill in your question
Enter the items that you want your audience to rank
Once you get responses on your Ranking question, the items will rearrange themselves according to the order that the audience have put them in. Items that weren't selected will be displayed at the bottom.
With the ranking question type, the audience can choose to rank all the items you have provided, or just a few of them.
How the ranking is calculated
The ranking question is calculated with a 'points' system, where the item ranked first, will get as many points as the total number of items you have in your question, and then descending. So if you have 5 items, the one put on 1st place gets 5 points and then descending. If an item doesn't get selected it means 0 points.
