I have a list of items L, in alphabetic order, that I want students to rank on personal preference (i.e. no correct order). Using an ordered list, each student can put the items into their desired order and the final choice can be extracted as a list C. On the next screen I’d then like to display a table showing their preference order P against the original alphabetic list L. So, if this were a list of holiday destinations and the third item was put top, there would be a 1 against the third item in the table. In formulaic terms, this would be P[C] = 1 but with my lack of experience I can’t work out how to do that in Desmos. Apologies if it is trivial!
I can invite the students to put the preference numbers directly into the table but validating what they enter is then tricky.
