Ranking items in MediaLab (case 1678)

[jarvis]

I don't believe there is a way to constrain like that. Aside from instructions, perhaps, to select three of the fourteen items. Although I think you will hit a 12 item limit if I recall correctly. You could also try this with a multiple response item (see users guide). Again, you'd be limited to 12, but by using the parameters (p12,r1-3), the latter range parameter would force the subject into selecting between 1 and 3 of the alternatives. Then using the variable names from the data file, you might be able to work out some kind of ranking procedure for just those three items that are selected.
