I need to prepare a workshop and at the end of the workshop I want participants to choose from a set of questions (e.g. n=20) only x (e.g. x=5) questions to discuss. Therefore I want to give each participant a number of points (red spots) to distribute to the whole selection of questions.
Question: Is there a formula/theory that allows me to detect the right number of "voting points" that I have to give to each participant in order to find a limited number x of questions.
It would be great if anybody could help me!
